Sorry for digging up an old thread, but I’ve been messing with AnyConnect today and had the same issue.
First, /url][/url»>@nkalister][/url][/url is right — the default AnyConnect installer does work fine. However, I haven’t yet been able to get it to install without the Web Security, Posture, and DART modules. I tried using the ACTransforms.xml file mentioned in the documentation ([http://www.cisco.com/en/US/docs/security/vpn_client/anyconnect/anyconnect31/administration/guide/ac02asaconfig.html#wp1612894), but I haven’t had any luck. It would help if they listed all of the properties… If anyone knows how to use the default AnyConnect package but not install specific modules, please let me know.
So, I ended up using the snapshot method to lay down the files, but then of course I get the error «No components loaded. Quitting application.» However, AnyConnect works fine after a reboot. While that would probably be acceptable, I wasn’t satisfied. This led me to do a little research and figure out that vpnagentd needed to be running. So, I wrote a one line post install script to run the following command:
#!/bin/sh
#Launches the vpnagentd process; if this isn't running, AnyConnect doesn't run
/opt/cisco/anyconnect/bin/vpnagentd
So, lay down the files and run a post install script to run vpnagentd. Also don’t forget to include your profile.xml file in /opt/cisco/anyconnect/vpn/profile. You can either manually add it to the package, or have it copied during the install by having it in the Profile directory in the same location as the AnyConnect.pkg file.
Hope this helps someone.
Disclaimer: I used PackageMaker to build my AnyConnect .pkg, but I’m sure Composer will work too.
Looks like no one’s replied in a while. To start the conversation again, simply
ask a new question.
Nothing has changed on tehe VPN server side our network admins says, but was working fine yesterday morning on the 25.feb 2020, but this morning our Macs fails to connect to our ASA gateway. Was running versions of Cisco AnyConnect <= 4.1.04011, after restarting these clients they now says «No components loaded.» and then quits. Newer versions all up to 4.8.02045 still fails to with the error: «The VPN client was unable to successfully verify the IP forwarding table modifications. A VPN connection will not be established.».
So right now we Macs users are in a pickle, internal IT don’t wants to/are not able to support Mac users, hence we’ve been forced not to upgrade to MacOS 10.15 Catalina, but now VPN even fails for MacOS Mojave 10.14 :/
Did something change in MacOS that automatically updated over night?

VPN (Cisco IPSec)
Since the update to Big Sur Mac OS 11.0.1 VPN Cisco IPSec does not work anymore.My VPN services created on the default system VPN Type Cisco IPSec still do connect, but afterwards there is no IP traffic possible. Not even pings to IP addresses are possible.
I’ve looked into potential firewall issues, re-created the services on Big Sur and checked from Catalina and iOS where the VPN entries are still working flawlessly.Any ideas?

Forticlient error: «Internal error. VPN status observer is already set.»
I’m trying to get my work VPN working on a new Mac Mini (M1, 2021) running Mac OS 12.6. When I try to connect with Forticlient free VPN software, I am asked for the token digits and can get through that, but then I get a message: «Internal error. VPN status observer is already set.»This does not happen on my 2015 MacBook Pro also running Mac OS 12.6. So it’s not an operating system problem. I also did a reinstall of Mac OS on the new Mac Mini and that did not fix the problem. Also, since I can access the VPN using the MacBook Pro and my iPad, the issue is not my personal account.
Anyone else see this message and know what it could be about?
One potential clue: in setting up the Mac Mini, I used Migration Assistant to transfer data from a 2013 iMac running Catalina. It’s possible some bad files are buried in the system—any suggestions for a good uninstaller (better than the Fortinet uninstaller) or what should be deleted?

Cisco AnyConnect VPN stopped working today, why?
На чтение 3 мин. Просмотров 3.2k. Опубликовано 03.09.2019
Использование VPN-клиента, такого как Cisco AnyConnect, должно обеспечить беспрецедентный доступ к конечной точке как для ваших сотрудников, так и для вас. Преимущества использования такой услуги более чем очевидны, поскольку вы можете получить удаленный доступ к сети компании с любого ПК или мобильного устройства.
Тем не менее, даже несмотря на то, что редкая проблема может омрачить общую функциональность, их обычно просто разобрать. Сегодня мы обращаемся к ошибке «VPN не удалось загрузить настройки».
Эта ошибка не позволяет пользователям подключаться к сети VPN.
Содержание
- Что делать, если VPN не удалось загрузить настройки
- Решение 1 – Переустановите клиент
- Решение 2 – Удалить папку Cisco
- Решение 3 – Изменить настройки безопасности
- Решение 4 – Удалить профиль XML
Что делать, если VPN не удалось загрузить настройки
- Переустановите клиент
- Удалите папку Cisco
- Изменить настройки безопасности
- Удалить профиль XML
Решение 1 – Переустановите клиент
Первый довольно очевидный шаг – попытаться переустановить клиент. Некоторые пользователи предполагают, что определенная версия AnyConnect не будет работать, поэтому вы можете получить ее после приобретения более поздней версии. Вы не начнете с нуля, так как файлы конфигурации и профиля ProgramData останутся нетронутыми.
После удаления VPN-клиента Cisco AnyConnect перейдите на официальный веб-сайт и загрузите свежий установщик. Если проблема не устранена, перейдите к следующему шагу.
Решение 2 – Удалить папку Cisco
Возможное повреждение файлов конфигурации может привести к таким проблемам. Поскольку возникает ошибка «VPN не удалось загрузить настройки», клиент не может получить настройки, по которым настроен клиент.
Чтобы решить эту проблему, вы можете попробовать удалить все связанные файлы настроек из нескольких мест.
Вот файлы, которые вы должны удалить:
- % ProgramData% CiscoCisco AnyConnect Secure Mobility ClientProfile
- % AppData% LocalCiscoCisco AnyConnect Secure Mobility Client
Удаление этой папки приведет к удалению всех настроек. Некоторые пользователи предлагают переустановить клиент после этого, но вы можете сначала попробовать его, а затем действовать соответствующим образом, если проблема не устранена.

Решение 3 – Изменить настройки безопасности
Кажется, есть еще одна возможная причина ошибки «VPN не удалось загрузить настройки». А именно, похоже, что это мешает только пользователям, у которых не включены необходимые разрешения доступа. Вы можете исправить это, и, надеюсь, это решит проблему. Вот что вам нужно сделать:
- Перейдите на % ProgramData% CiscoCisco AnyConnect Secure Mobility Client .
- Нажмите правой кнопкой мыши папку Профиль и откройте Свойства .
- Выберите вкладку Безопасность .
- Нажмите «Изменить» (для этого понадобится административное разрешение).
- Установите флажок « Полный контроль » и подтвердите изменения.
Решение 4 – Удалить профиль XML
Наконец, если ни одно из предыдущих решений не помогло устранить ошибку, у нас есть еще одна вещь, которую вы можете попробовать. Конечно, всегда есть возможность связаться со службой поддержки и отправить им все необходимые журналы, чтобы они могли вам помочь. Просто, прежде чем сделать это, попробуйте эти шаги:
-
- Включите псевдоним группы или URL группы для туннельных групп.
- Создайте резервную копию профиля XML и удалите его из устройства адаптивной безопасности.
-
Теперь удалите (удалите) следующие файлы с зараженного компьютера:
- preferences.xml
- preferences_global.xml
- Профиль XML в папке Профили .
- Наконец, переподключите клиента.
С учетом сказанного мы можем завершить эту статью. Если у вас есть какие-либо вопросы или предложения, не стесняйтесь сообщить нам в разделе комментариев ниже.

Я пытаюсь подключиться к VPN на своем рабочем месте, но Cisco AnyConnect не работает после запуска соединения. Появляется ошибка с сообщением The VPN client failed to establish a connection , после чего появляется другая ошибка: AnyConnect was not able to establish a connection to the specified secure gateway. Please try connecting again. Я все пробовал. Переустановка, перезапуск и другие другие функции, такие как отключение ICS (общий доступ к подключению Интернета). Я попробовал это на своем ноутбуке, и веб-установщик работал нормально. Он установил клиента и подключился отлично, так что это должно быть что-то с этим ПК. Я пытаюсь понять это примерно в течение 5 часов, и Google не помогает. Вот история сообщений от AnyConnect:

Я попытался отключить брандмауэр и антивирус. Я не думал, что это будет иметь значение, поскольку мой ноутбук использует тот же брандмауэр и антивирус, и мне не нужно было его отключать. Мой ноутбук использует Windows 7 Home 64-bit, а мой компьютер с ошибкой использует 64-разрядную версию Windows 7 Ultimate.

Решением для меня было отключить общий доступ к подключению Интернета (ICS).
Чтобы устранить эту проблему:
- Нажмите кнопку Windows Start .
- Нажмите Control Panel .
- Установите View by: в Category .
- Нажмите View network status and tasks в Network and Internet .
- Нажмите Change adapter settings .
- Найдите Shared в столбце Status и щелкните его правой кнопкой мыши и нажмите Properties .
- Перейдите на вкладку Sharing .
- Снимите флажок Allow other network users to connect through this computer’s Internet connection .
- Нажмите OK .
- Переустановите Cisco AnyConnect.
Я вижу, что отключение ICS не работало для OP, но это работало для меня и многих других, по мнению различных форумов, кажется.
Это может быть проблема с ThinkPad. Lenovo опубликовала рекомендательную статью , указывающую, что их программное обеспечение Access Connections мешает AnyConnect. Решение состоит в отключении ICS. У меня нет способа установить, является ли это фактической причиной моей проблемы, но решение работает.
ответ Натана на этой странице не работал для меня, потому что флажки Allow other network users[. ] были очищены для всех все равно.
Я отключил ICS таким образом:
Введите services.msc в меню Windows после нажатия кнопки «Пуск». Щелкните правой кнопкой мыши на services.msc , который появляется после завершения поиска, и Run as Administrator.
Найдите Internet Connection Sharing , остановите его и установите для запуска Manually .

Problem
We had a firewall fail at work this week, as part of the rebuild the latest OS was put on it, version 9.7(1). I thought no more about it until I tried to VPN in and got this;
I used my Windows 10 VM and that connected fine, only my MacBook could not connect, this VPN tunnel is a big deal I need it to get onto client’s networks. I tried my other VPN connections and every one was fine, only the recently rebuilt one didn’t work? Ive seen OSX throw a wobbly with AnyConnect in the past so I did a complete uninstall, В deleted the opt/cisco folder and put on the latest version (4.4.00243 at time of writing) no change.
Connection attempt has failed due to server communication errors. Please retry the connection
A look in the client message history showed me this..
No valid certificates available for authentication.
I checked my certificates, and the certificate on the firewall both they, (and the certificate chain,) were fine.
Debugging AnyConnect gave NO OUTPUT at all, but debugging SSL showed me this;
Try Googling that and getting a result! In fact that’s probably what brought you here.
Solution
If you change a Cisco OS and things like this stop working normally it’s because they’ve dropped support for something that’s got a security hole in it. In the wake of the Poodle Exploit I assumed it was an SSL/TLS problem, but that wasn’t it.
I was in the right ball park though, and a bit of lateral thinking and SSL cipher problems I’ve had with ASDM, made me think, what if it’s SHA that’s been dropped because everyone is dropping SHA1 cause it’s the hashing algorithm of Satan?
Well as soon as I added a SHA1 ciphers back in, everything started working again!
Disclaimer: SHA1 is bad, where practical all cert ciphers should be at least SHA256

Hi all, I’m very new in AnyConnect and I’m doing something wrong.
If I navigate to https://myIP I can successfully log into the portal, download and install the AnyConnect Client and also CONNECT to the VPN.
But if I disconnect to the VPN, and try to login again through the try icon, I get a «connection attempt has failed».
So the only way I have to connect again is to navigate another time to the web portal and then, after login again, the VPN connection is successfully done.
Thanks for your help!

Are you using a Router or ASA has the VPN gateway? If you are using an ASA, check your DAP policy under Configuration, Network (Client) Access, Dynamic Access Policies. If there are policies there, chose the profile that is mapped to the tunnel you are connecting too and then go to «Access Method». Ensure «Web Portal» isn’t checked. If you want to be able use the portal and the client, you need to change it to one of the «Both» choices. If there is no DAP, we’ll have to dig a little deeper.

Hello Christopher, thanks for your answer.
I’m using an ASA, and in DAP I only have the DfltAccess, and I changed the Access Method from Unchanged to Both, but I have the same problem.
Now I have a question (sorry if it is obvious), using the portal, I provide the login/passwd, but using only the client it doesn’t ask me for credentials, it only shows the certificate error (cause it is self-signed), and when I accept it, the connection fails.

When you go to login through the AC client, what is in the «Connect To:» box? It may be an issue regarding the AC profile that gets downloaded after successfully logging in and downloading the client via web portal.

Hi, in the connect To box there is the public IP of the ASA, so I think it might be correct. Then appears an Untrusted VPN Certificate warning, and after clicking «Connect Anyway» it shows the error.
I have the anyconnect-win-3.1.04063-k9.pkg client software, should I try a lower version?
Maybe I’ll try to create the certificate through a Windows Server CA and then import to ASA and to the client, so see if it solves the issue.

First try this. Open the AnyConnect Client, go to the Preferrences tab, and make sure the box that says «Block Untrusted Servers» is NOT checked.

Hi Christopher, that was the first I have to do in order to be able to connect when I connect to the VPN (through the web) for the first time. So I can confirm it is unchecked.
Thanks for the advice

Do you have access to ASDM or a syslog server? It would be best if you could grab the exact error message in the logs when you try to connect.
Also, if you are using ASDM — make sure you have «Enable Cisco AnyConnect VPN Client Access on the intefaces in the table below» checked. Assuming you are using the «outside» interface, check that one and enable DTLS. Then click «Device Certificate» and make sure you have the correct certificate chosen for the SSL connection (probably the ASAs self signed certificate».
Make sure «Bypass interface access lists for inbound VPN sessions» is checked as well.

Introduction
This document describes a troubleshooting scenario which applies to applications that do not work through the Cisco AnyConnect VPN Client.
Prerequisites
Requirements
There are no specific requirements for this document.
Components Used
The information in this document is based on a Cisco Adaptive Security Appliance (ASA) that runs Version 8.x.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Troubleshooting Process
This typical troubleshooting scenario applies to applications that do not work through the Cisco AnyConnect VPN Client for end-users with Microsoft Windows-based computers. These sections address and provide solutions to the problems:
- Installation and Virtual Adapter Issues
- Disconnection or Inability to Establish Initial Connection
- Problems with Passing Traffic
- AnyConnect Crash Issues
- Fragmentation / Passing Traffic Issues
Installation and Virtual Adapter Issues
Complete these steps:
- Obtain the device log file:
- Windows XP / Windows 2000:
Windowssetupapi.log
- Windows Vista:
Note: Hidden folders must be made visible in order to see these files.
WindowsInfsetupapi.app.log
WindowsInfsetupapi.dev.log
If you see errors in the setupapi log file, you can turn up verbosity to 0x2000FFFF.
- Windows XP / Windows 2000:
- Obtain the MSI installer log file:
If this is an initial web deploy install, this log is located in the per-user temp directory.
- Windows XP / Windows 2000:
Documents and Settings<username>Local SettingsTemp
- Windows Vista:
Users<username>AppDataLocalTemp
If this is an automatic upgrade, this log is in the temp directory of the system:
WindowsTemp
The filename is in this format: anyconnect-win-x.x.xxxx-k9-install-yyyyyyyyyyyyyy.log. Obtain the most recent file for the version of the client you want to install. The x.xxxx changes based on the version, such as 2.0.0343, and yyyyyyyyyyyyyy is the date and time of the install.
- Windows XP / Windows 2000:
- Obtain the PC system information file:
- From a Command Prompt/DOS box, type this:
- Windows XP / Windows 2000:
winmsd /nfo c:msinfo.nfo
- Windows Vista:
msinfo32 /nfo c:msinfo.nfo
Note: After you type into this prompt, wait. It can take between two to five minutes for the file to complete.
- Windows XP / Windows 2000:
- Obtain a systeminfo file dump from a Command Prompt:
Windows XP and Windows Vista:
systeminfo c:sysinfo.txt
- From a Command Prompt/DOS box, type this:
Refer to AnyConnect: Corrupt Driver Database Issue in order to debug the driver issue.
Disconnection or Inability to Establish Initial Connection
If you experience connection problems with the AnyConnect client, such as disconnections or the inability to establish an initial connection, obtain these files:
- The configuration file from the ASA in order to determine if anything in the configuration causes the connection failure:
From the console of the ASA, type
write net x.x.x.x:ASA-Config.txt
wherex.x.x.x
is the IP address of a TFTP server on the network.OR
From the console of the ASA, type
show running-config
. Let the configuration complete on the screen, then cut-and-paste to a text editor and save. - The ASA event logs:
- In order to enable logging on the ASA for auth, WebVPN, Secure Sockets Layer (SSL), and SSL VPN Client (SVC) events, issue these CLI commands:
config terminal
logging enable
logging timestamp
logging class auth console debugging
logging class webvpn console debugging
logging class ssl console debugging
logging class svc console debugging - Originate an AnyConnect session and ensure that the failure can be reproduced. Capture the logging output from the console to a text editor and save.
- In order to disable logging, issue
no logging enable
.
- In order to enable logging on the ASA for auth, WebVPN, Secure Sockets Layer (SSL), and SSL VPN Client (SVC) events, issue these CLI commands:
- The Cisco AnyConnect VPN Client log from the Windows Event Viewer of the client PC:
- Choose Start > Run.
- Enter:
eventvwr.msc /s
- Right-click the Cisco AnyConnect VPN Client log, and select Save Log File as AnyConnect.evt.
Note: Always save it as the .evt file format.
If the user cannot connect with the AnyConnect VPN Client, the issue might be related to an established Remote Desktop Protocol (RDP) session or Fast User Switching enabled on the client PC. The user can see the AnyConnect profile settings mandate a single local user, but multiple local users are currently logged into your computer. A VPN connection will not be established error message
error on the client PC. In order to resolve this issue, disconnect any established RDP sessions and disable Fast User Switching. This behavior is controlled by the Windows Logon Enforcement attribute in the client profile, however currently there is no setting that actually allows a user to establish a VPN connection while multiple users are logged on simultaneously on the same machine. Enhancement request CSCsx15061 was filed to address this feature.
Note: Make sure that port 443 is not blocked so the AnyConnect client can connect to the ASA.
When a user cannot connect the AnyConnect VPN Client to the ASA, the issue might be caused by an incompatibility between the AnyConnect client version and the ASA software image version. In this case, the user receives this error message: The installer was not able to start the Cisco VPN client, clientless access is not available
.
In order to resolve this issue, upgrade the AnyConnect client version to be compatible with the ASA software image.
When you log in the first time to the AnyConnect, the login script does not run. If you disconnect and log in again, then the login script runs fine. This is the expected behavior.
When you connect the AnyConnect VPN Client to the ASA, you might receive this error: User not authorized for AnyConnect Client access, contact your administrator
.
This error is seen when the AnyConnect image is missing from the ASA. Once the image is loaded to the ASA, AnyConnect can connect without any issues to the ASA.
This error can be resolved by disabling Datagram Transport Layer Security (DTLS). Go to Configuration > Remote Access VPN > Network (Client) Access > AnyConnect Connection Profiles and uncheck the Enable DTLS check box. This disables DTLS.
The dartbundle files show this error message when the user gets disconnected: TUNNELPROTOCOLDPDMGR_ERROR_NO_DPD_RESPONSE:The secure gateway failed to respond to Dead Peer Detection packets
. This error means that the DTLS channel was torn due to Dead Peer Detection (DPD) failure. This error is resolved if you tweak the DPD keepalives and issue these commands:
webvpn
svc keepalive 30
svc dpd-interval client 80
svc dpd-interval gateway 80
The svc keepalive and svc dpd-interval commands are replaced by the anyconnect keepalive and anyconnect dpd-interval commands respectively in ASA Version 8.4(1) and later as shown here:
webvpn
anyconnect ssl keepalive 15
anyconnect dpd-interval client 5
anyconnect dpd-interval gateway 5
Problems with Passing Traffic
When problems are detected with passing traffic to the private network with an AnyConnect session through the ASA, complete these data-gathering steps:
- Obtain the output of the show vpn-sessiondb detail svc filter name <username> ASA command from the console. If the output shows
Filter Name: XXXXX
, then gather the output for show access-list XXXXX. Verify that the access-list XXXXX does not block the intended traffic flow. - Export the AnyConnect statistics from AnyConnect VPN Client > Statistics > Details > Export (AnyConnect-ExportedStats.txt).
- Check the ASA configuration file for nat statements. If Network Address Translation (NAT) is enabled, these must exempt data that returns to the client as a result of NAT. For example, to NAT exempt (nat 0) the IP addresses from the AnyConnect pool, use this on the CLI:
access-list in_nat0_out extended permit ip any 10.136.246.0 255.255.255.0
ip local pool IPPool1 10.136.246.1-10.136.246.254 mask 255.252.0.0
nat (inside) 0 access-list in_nat0_out - Determine if the tunneled default gateway needs to be enabled for the setup. The traditional default gateway is the gateway of last resort for non-decrypted traffic.
Example:
!--- Route outside 0 0 is an incorrect statement.
route outside 0 0 10.145.50.1
route inside 0 0 10.0.4.2 tunneledFor example, if the VPN Client needs to access a resource which is not in the routing table of the VPN Gateway, the packet is routed through the standard default gateway. The VPN gateway does not need the complete internal routing table in order to resolve this. The tunneled keyword can be used in this instance.
- Verify if the AnyConnect traffic is dropped by the inspection policy of the ASA. You could exempt the specific application that is used by AnyConnct client if you implement the Modular Policy Framework of Cisco ASA. For example, you could exempt the skinny protocol with these commands.
ASA(config)# policy-map global_policy
ASA(config-pmap)# class inspection_default
ASA(config-pmap-c)# no inspect skinny

Fragmentation / Passing Traffic Issues
Some applications, such as Microsoft Outlook, do not work. However, the tunnel is able to pass other traffic such as small pings.
This can provide clues as to a fragmentation issue in the network. Consumer routers are particularly poor at packet fragmentation and reassembly.
Try a scaling set of pings in order to determine if it fails at a certain size. For example, ping -l 500, ping -l 1000, ping -l 1500, ping -l 2000.
It is recommended that you configure a special group for users that experience fragmentation, and set the SVC Maximum Transition Unit (MTU) for this group to 1200. This allows you to remediate users who experience this issue, but not impact the broader user base.
Problem
TCP connections hang once connected with AnyConnect.
Solution
In order to verify if your user has a fragmentation issue, adjust the MTU for AnyConnect clients on the ASA.
ASA(config)#group-policy <name> attributes
webvpn
svc mtu 1200
Uninstall Automatically
Problem
The AnyConnect VPN Client uninstalls itself once the connection terminates. The client logs show that keep installed is set to disabled.
Solution
AnyConnect uninstalls itself despite that the keep installed option is selected on the Adaptive Security Device Manager (ASDM). In order to resolve this issue, configure the svc keep-installer installed command under group-policy.
Issue Populating the Cluster FQDN
Problem: AnyConnect client is pre-populated with the hostname instead of the cluster Fully Qualified Domain Name (FQDN).
When you have a load-balancing cluster set up for SSL VPN and the client attempts to connect to the cluster, the request is redirected to the node ASA and the client logs in successfully. After some time, when the client tries to connect to the cluster again, the cluster FQDN is not seen in the Connect to entries. Instead, the node ASA entry to which the client has been redirected is seen.
Solution
This occurs because the AnyConnect client retains the host name to which it last connected. This behavior is observed and a bug has been filed. For complete details about the bug, refer to Cisco bug ID CSCsz39019. The suggested workaround is to upgrade the Cisco AnyConnect to Version 2.5.
Backup Server List Configuration
A backup server list is configured in case the main server selected by the user is not reachable. This is defined in the Backup Server pane in the AnyConnect profile. Complete these steps:
- Download the AnyConnect Profile Editor (registered customers only) . The file name is AnyConnectProfileEditor2_4_1.jar.
- Create an XML file with the AnyConnect Profile Editor.
- Go to the server list tab.
- Click Add.
- Type the main server on the Hostname field.
- Add the backup server below the backup server list on the Host address field. Then, click Add.
- Once you have the XML file, you need to assign it to the connection you use on the ASA.
- In ASDM, choose Configuration > Remote Access VPN > Network (Client) Access > AnyConnect Connection Profiles.
- Select your profile and click Edit.
- Click Manage from the Default Group Policy section.
- Select your group-policy and click Edit.
- Select Advanced and then click SSL VPN Client.
- Click New. Then, you need to type a name for the Profile and assign the XML file.
- Connect the client to the session in order to download the XML file.

While the SSL VPN is connected through a web browser, the Unable to Update the Session Management Database.
error message appears, and the ASA logs show %ASA-3-211001: Memory allocation Error. The adaptive security appliance failed to allocate RAM system memory
.
Solution 1
This issue is due to Cisco bug ID CSCsm51093. In order to resolve this issue, reload the ASA or upgrade the ASA software to the interim release mentioned in the bug. Refer to Cisco bug ID CSCsm51093 for more information.
Solution 2
This issue can also be resolved if you disable threat-detection on ASA if threat-detection is used.
Error: «Module c:Program FilesCiscoCisco AnyConnect VPN Clientvpnapi.dll failed to register»
When you use the AnyConnect client on laptops or PCs, an error occurs during the install:
"Module C:Program FilesCiscoCisco AnyConnect VPN Clientvpnapi.dll failed
to register..."
When this error is encountered, the installer cannot move forward and the client is removed.
Solution
These are the possible workarounds to resolve this error:
- The latest AnyConnect client is no longer officially supported with Microsoft Windows 2000. It is a registry problem with the 2000 computer.
- Remove the VMware applications. Once AnyConnect is installed, VMware applications can be added back to the PC.
- Add the ASA to their trusted sites.
- Copy these files from the ProgramFilesCiscoCiscoAnyconnect folder to a new folder and run the regsvr32 vpnapi.dll command prompt:
- vpnapi.dll
- vpncommon.dll
- vpncommoncrypt.dll
- Reimage the operating system on the laptop/PC.
The log message related to this error on the AnyConnect client looks similar to this:

Error: «An error was received from the secure gateway in response to the VPN negotiation request. Please contact your network administrator»
When clients try to connect to the VPN with the Cisco AnyConnect VPN Client, this error is received.
This message was received from the secure gateway:
«Illegal address class» or «Host or network is 0» or «Other error»
Solution
The issue occurs because of the ASA local IP pool depletion. As the VPN pool resource is exhausted, the IP pool range must be enlarged.
Cisco bug ID is CSCsl82188 is filed for this issue. This error usually occurs when the local pool for address assignment is exhausted, or if a 32-bit subnet mask is used for the address pool. The workaround is to expand the address pool and use a 24-bit subnet mask for the pool.
Error: Session could not be established. Session limit of 2 reached.
When you try to connect more than two clients with the AnyConnect VPN Client, you receive the Login Failed
error message on the Client and a warning message in the ASA logs that states Session could not be established. Session limit of 2 reached
. I have the AnyConnect essential license on the ASA, which runs Version 8.0.4.
Solution 1
This error occurs because the AnyConnect essential license is not supported by ASA version 8.0.4. You need to upgrade the ASA to version 8.2.2. This resolves the error.
Note: Regardless of the license used, if the session limit is reached, the user will receive the login failed
error message.
Solution 2
This error can also occur if the vpn-sessiondb max-anyconnect-premium-or-essentials-limit session-limit command is used to set the limit of VPN sessions permitted to be established. If the session-limit is set as two, then the user cannot establish more than two sessions even though the license installed supports more sessions. Set the session-limit to the number of VPN sessions required in order to avoid this error message.
Error: Anyconnect not enabled on VPN server while trying to connect anyconnect to ASA
You receive the Anyconnect not enabled on VPN server
error message when you try to connect AnyConnect to the ASA.
Solution
This error is resolved if you enable AnyConnect on the outside interface of the ASA with ASDM. For more information on how to enable AnyConnect on the outside interface, refer to Configure Clientless SSL VPN (WebVPN) on the ASA.
Error:- %ASA-6-722036: Group client-group User xxxx IP x.x.x.x Transmitting large packet 1220 (threshold 1206)
The %ASA-6-722036: Group < client-group > User < xxxx > IP < x.x.x.x> Transmitting large packet 1220 (threshold 1206)
error message appears in the logs of the ASA. What does this log mean and how is this resolved?
Solution
This log message states that a large packet was sent to the client. The source of the packet is not aware of the MTU of the client. This can also be due to compression of non-compressible data. The workaround is to turn off the SVC compression with the svc compression none command. This resolves the issue.
Error: The secure gateway has rejected the agent’s vpn connect or reconnect request.
When you connect to the AnyConnect Client, this error is received: "The secure gateway has rejected the agent's vpn connect or reconnect request. A new connection requires re-authentication and must be started manually. Please contact your network administrator if this problem persists. The following message was received from the secure gateway: no assigned address"
.
This error is also received when you connect to the AnyConnect Client: "The secure gateway has rejected the connection attempt. A new connection attempt to the same or another secure gateway is needed, which requires re-authentication. The following message was received from the secure gateway:Host or network is 0"
.
This error is also received when you connect to the AnyConnect Client: "The secure gateway has rejected the agent's vpn connect or reconnect request. A new connection requires a re-authentication and must be started manually. Please contact the network administrator if the problem persists. The following message was received from the secure gateway: No License"
.
Solution
The router was missing pool configuration after reload. You need to add the concerned configuration back to the router.
Router#show run | in pool
ip local pool SSLPOOL 192.168.30.2 192.168.30.254
svc address-pool SSLPOO
The "The secure gateway has rejected the agent's vpn connect or reconnect request. A new connection requires a re-authentication and must be started manually. Please contact the network administrator if the problem persists. The following message was received from the secure gateway: No License"
error occurs when the AnyConnect mobility license is missing. Once the license is installed, the issue is resolved.
Error: «Unable to update the session management database»
When you try to authenticate in WebPortal, this error message is received: "Unable to update the session management database"
.
Solution
This problem is related to memory allocation on the ASA. This issue is mostly encountered when the ASA Version is 8.2.1. Originally, this requires a 512MB RAM for its complete functionality.
As a permanent workaround, upgrade the memory to 512MB.
As a temporary workaround, try to free the memory with these steps:
- Disable the threat-detection.
- Disable SVC compression.
- Reload the ASA.
Error: «The VPN client driver has encountered an error»
This is an error message obtained on the client machine when you try to connect to AnyConnect.
Solution
In order to resolve this error, complete this procedure in order to manually set the AnyConnect VPN agent to Interactive:
- Right-click My Computer > Manage > Services and Applications > Services > and select the Cisco AnyConnect VPN Agent.
- Right-click Properties, then log on, and select Allow service to interact with the desktop.
This sets the registry Type value DWORD to 110 (default is 010) for the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesvpnagent.
Note: If this is to be used, then the preference would be to use the .MST transform in this instance. This is because if you set this manually with these methods, it requires that this be set after every install/upgrade process. This is why there is a need to identify the application that causes this problem.
When Routing and Remote Access Service (RRAS) is enabled on the Windows PC, AnyConnect fails with the
The VPN client driver has encountered an error.
error message. In order to resolve this issue, make sure that Routing and RRAS is disabled before starting AnyConnect. Refer to Cisco bug ID CSCsm54689 for more information.

Error: «Secure VPN via remote desktop is not supported»
Users are unable to perform a remote desktop access. The Secure VPN via remote desktop is not supported
error message appears.
Solution
This issue is due to these Cisco bug IDs: CSCsu22088 and CSCso42825. If you upgrade the AnyConnect VPN Client, it can resolve the issue. Refer to these bugs for more information.
Error: «The server certificate received or its chain does not comply with FIPS. A VPN connection will not be established»
When you attempt to VPN to the ASA 5505, the The server certificate received or its chain does not comply with FIPS. A VPN connection will not be established
error message appears.
Solution
In order to resolve this error, you must disable the Federal Information Processing Standards (FIPS) in the AnyConnect Local Policy file. This file can usually be found at C:ProgramDataCiscoCisco AnyConnect VPN ClientAnyConnectLocalPolicy.xml
. If this file is not found in this path, then locate the file at a different directory with a path such as C:Documents and SettingsAll UsersApplication DataCisco AnyConnectVPNClientAnyConnectLocalPolicy.xml
. Once you locate the xml file, make changes to this file as shown here:
Change the phrase:
<FipsMode>true</FipsMode>
To:
<FipsMode>false</FipsMode>
Then, restart the computer. Users must have administrative permissions in order to modify this file.
Error: «Certificate Validation Failure»
Users are unable to launch AnyConnect and receive the Certificate Validation Failure
error.
Solution
Certificate authentication works differently with AnyConnect compared to the IPSec client. In order for certificate authentication to work, you must import the client certificate to your browser and change the connection profile in order to use certificate authentication. You also need to enable this command on your ASA in order to allow SSL client-certificates to be used on the outside interface:
ssl certificate-authentication interface outside port 443
Error: «VPN Agent Service has encountered a problem and needs to close. We are sorry for the inconvenience»
When AnyConnect Version 2.4.0202 is installed on a Windows XP PC, it stops at updating localization files and an error message shows that the vpnagent.exe fails.
Solution
This behavior is logged in Cisco bug ID CSCsq49102. The suggested workaround is to disable the Citrix client.
Error: «This installation package could not be opened. Verify that the package exists»
When AnyConnect is downloaded, this error message is received:

AnyConnect Error While Logging In
Problem
The AnyConnect receives this error when it connects to the Client:
The VPN connection is not allowed via a local proxy. This can be changed
through AnyConnect profile settings.
Solution
The issue can be resolved if you make these changes to the AnyConnect profile:
Add this line to the AnyConnect profile:
<ProxySettings>IgnoreProxy</ProxySettings><
AllowLocalProxyConnections>
false</AllowLocalProxyConnections>
IE Proxy Setting is Not Restored after AnyConnect Disconnect on Windows 7
Problem
In Windows 7, if the IE proxy setting is configured for Automatically detect settings and AnyConnect pushes down a new proxy setting, the IE proxy setting is not restored back to Automatically detect settings after the user ends the AnyConnect session. This causes LAN issues for users who need their proxy setting configured for Automatically detect settings.
Solution
This behavior is logged in Cisco bug ID CSCtj51376. The suggested workaround is to upgrade to AnyConnect 3.0.
Error: AnyConnect Essentials can not be enabled until all these sessions are closed.
This error message is received on Cisco ASDM when you attempt to enable the AnyConnect Essentials license:
There are currently 2 clientless SSL VPN sessions in progress. AnyConnect
Essentials can not be enabled until all these sessions are closed.
Solution
This is the normal behavior of the ASA. AnyConnect Essentials is a separately licensed SSL VPN client. It is entirely configured on the ASA and provides the full AnyConnect capability, with these exceptions:
- No Cisco Secure Desktop (CSD) (including HostScan/Vault/Cache Cleaner)
- No clientless SSL VPN
- Optional Windows Mobile Support
This license cannot be used at the same time as the shared SSL VPN premium license. When you need to use one license, you need to disable the other.
Error: Connection tab on Internet option of Internet Explorer hides after getting connected to the AnyConnect client.
The connection tab on the Internet option of Internet Explorer hides after you are connected to the AnyConnect client.
Solution
This is due to the msie-proxy lockdown feature. If you enable this feature, it hides the Connections tab in Microsoft Internet Explorer for the duration of an AnyConnect VPN session. If you disable the feature, it leaves the display of the Connections tab unchanged.
Error: Few users getting Login Failed Error message when others are able to connect successfully through AnyConnect VPN
A few users receive the Login Failed Error message when others can connect successfully through the AnyConnect VPN.
Solution
This issue can be resolved if you make sure the do not require pre-authentication checkbox is checked for the users.
Error: The certificate you are viewing does not match with the name of the site you are trying to view.
During the AnyConnect profile update, an error is shown that says the certificate is invalid. This occurs with Windows only and at the profile update phase. The error message is shown here:
The certificate you are viewing does not match with the name of the site
you are trying to view.
Solution
This can be resolved if you modify the server list of the AnyConnect profile in order to use the FQDN of the certificate.
This is a sample of the XML profile:
<ServerList><HostEntry>
<HostName>vpn1.ccsd.net</HostName>
</HostEntry>
</ServerList>
Note: If there is an existing entry for the Public IP address of the server such as <HostAddress>
, then remove it and retain only the FQDN of the server (for example, <HostName>
but not <Host Address>
).
Cannot Launch AnyConnect From the CSD Vault From a Windows 7 Machine
When the AnyConnect is launched from the CSD vault, it does not work. This is attempted on Windows 7 machines.
Solution
Currently, this is not possible because it is not supported.
AnyConnect Profile Does Not Get Replicated to the Standby After Failover
The AnyConnect 3.0 VPN client with ASA Version 8.4.1 software works fine. However, after failover, there is no replication for the AnyConnect profile related configuration.
Solution
This problem has been observed and logged under Cisco bug ID CSCtn71662. The temporary workaround is to manually copy the files to the standby unit.

This behavior is observed and logged under Cisco bug ID CSCtx28970. In order to resolve this, quit the AnyConnect application and relaunch. The connection entries reappear after relaunch.
Error Message: TLSPROTOCOL_ERROR_INSUFFICIENT_BUFFER
The AnyConnect client fails to connect and the Unable to establish a connection
error message is received. In the AnyConnect event log, the TLSPROTOCOL_ERROR_INSUFFICIENT_BUFFER
error is found.
Solution
This occurs when the headend is configured for split-tunneling with a very large split-tunnel list (approximately 180-200 entries) and one or more other client attributes are configured in the group-policy, such as dns-server.
In order to resolve this issue, complete these steps:
- Reduce the number of entries in the split-tunnel list.
- Use this configuration in order to disable DTLS:
group-policy groupName attributes
webvpn
svc dtls none
For more information, refer to Cisco bug ID CSCtc41770.
Error Message: «Connection attempt has failed due to invalid host entry»
The Connection attempt has failed due to invalid host entry
error message is received while AnyConnect is authenticated with the use of a certificate.
Solution
In order to resolve this issue, try either of these possible solutions:
- Upgrade the AnyConnect to Version 3.0.
- Disable Cisco Secure Desktop on your computer.
For more information, refer to Cisco bug ID CSCti73316.
Error: «Ensure your server certificates can pass strict mode if you configure always-on VPN»
When you enable the Always-On feature on AnyConnect, the Ensure your server certificates can pass strict mode if you configure always-on VPN
error message is received.
Solution
This error message implies that if you want to use the Always-On feature, you need a valid sever certificate configured on the headend. Without a valid server certificate, this feature does not work. Strict Cert Mode is an option that you set in the AnyConnect local policy file in order to ensure the connections use a valid certificate. If you enable this option in the policy file and connect with a bogus certificate, the connection fails.
