Вы тоже столкнулись с ошибкой ECONNREFUSED — connection refused by server в FileZilla? Тогда здорово, что вы нашли это руководство. Я покажу вам три метода, как можно исправить эту ошибку FTP.

Первый Метод. Изменение Дефолтного Значения Порта FileZilla

Причиной ошибки может быть неправильный порт при подключении через FileZilla. В этой ситуации вам просто нужно изменить порт FTP по умолчанию на дефолтный номер порта SFTP. Просто измените 21 на 22 в поле ввода “Port”.

Второй Метод. Отключение Антивируса/Брандмауэра

Иногда эта ошибка может возникать, когда антивирусное программное обеспечение и/или брандмауэр отказывает FileZilla в попытках установить соединение.

В случае, если антивирус или брандмауэр вызывает ECONNREFUSED, вам нужно просто отключить это ПО, а затем снова подключиться. Сначала я покажу вам, как это сделать в macOS:

  • Нажмите на иконку “Apple” в верхнем меню. Перейдите в “System Preferences”.
  • Найдите раздел настроек “Security & Privacy”.

  • Перейдите во вкладку “Firewall” и выберите “Turn Off Firewall”.

Если вы используете Windows, выполните следующие действия:

  • В строке поиска по Windows введите запрос “Control Panel”.
  • Затем перейдите в раздел “System & Security” и найдите “Windows Defender Firewall”.

  • В меню слева найдите “Turn Windows Defender Firewall on or off”.

  • Измените параметры, чтобы отключить брандмауэр Защитника Windows для общедоступных и частных сетей в следующем окне и нажмите “Ok”.

Подробней о том, как деактивировать разное антивирусное программное обеспечение можно прочитать здесь (англ).

Если отключение антивируса или брандмауэра не помогло и вы по-прежнему получаете ошибку «ECONNREFUSED — connection refused by server», попробуйте следующий метод.

Третий Метод. Изменение Мастера Настройки Сети FileZilla

Что делать, если предыдущие решения не принесли желаемого результата? Чтобы исправить ошибку, вы также можете попробовать изменить конфигурации сети FileZilla:

  • Подключитесь к FTP-клиенту FileZilla, затем перейдите в “Edit” и выберите “Network Configuration Wizard”.

  • Когда появится окно “Firewall and router configuration wizard”, нажмите “Next”, чтобы продолжить.
  • В качестве режима передачи по умолчанию выберите “Passive (recommended)”. Также отметьте галочкой “Allow fallback to another transfer mode on failure”.

  • Выберите “Use server’s external IP address instead”.
  • Выберите “Get the external IP address from the following URL”. Введите значение по умолчанию в случае, если поле ввода не заполнено (значение по умолчанию — это URL ip.filezilla-project.org/ip.php), нажмите “Next”, чтобы продолжить.
  • Не изменяйте настройки диапазона портов, просто выберите “Ask operating system for a port” и нажмите “Next”.

На этом этапе вам необходимо убедиться, что все настройки были выполнены правильно. Нажмите кнопку “Test”, чтобы FileZilla попыталась установить соединение с probe.filezilla-project.org. Программа выполнит несколько простых тестов.

Если тестирование пройдет без сбоев, попробуйте снова подключиться к вашей учетной записи хостинга. В этот раз все должно работать отлично. Если же ошибка ECONNREFUSED все равно не исчезла, обратитесь в службу поддержки вашего хостинга.

Выводы

Вот и все. Это и есть три метода, как исправить ошибку «ECONNREFUSED — connection refused by server». Надеемся, что один из них таки поможет вам решить проблему с FileZilla. Если у вас остались вопросы или вы знаете другие решения, не стесняйтесь оставить комментарий!

Why can’t I connect to the mysql server?

On the same server an Apache/PHP server is running and it connects without problems!?

var mysql_link = {
    host : 'localhost',
    port : 3308,
    database: 'nodetest',
    user : 'root',
    password : 'xxx'
};

var connection = mysql.createConnection(mysql_link);

connection.connect(function(err){
    console.log(err);
    if(err != null){
        response.write('Error connecting to mysql:' + err+'n');
    }
});

connection.end();

error

{ [Error: connect ECONNREFUSED]
  code: 'ECONNREFUSED',
  errno: 'ECONNREFUSED',
  syscall: 'connect',
  fatal: true }

I know this question has been answered, but for me the problem was that the mysql server listens on a Unix socket not on a tcp socket. So the solution was to add:

port: '/var/run/mysqld/mysqld.sock'

to the connection options.

If this has worked before, my first guess would be that you’ve already got a copy of your node.js script running in the background which is holding the connection.

I believe connection refused is a tcp/ip error message, rather than something from MySQL which suggests that it is either not running or is running on another port or with sockets.

Could you try telnet’ing to port 3308? To see if the server is running on that port?

telnet localhost 3308

Can you also try:

mysql -hlocalhost -uroot -pxxx

Overview

For anyone else having this problem and is running mamp. I suspected the problem had to do with the network and not MySQL or Node.js.

Solution

If you open MAMP and click MySQL in the left navigation panel it will pull up the MySQL options page. In the center of the page you will see a checkbox that says,

«Allow network access to MySQL«.

Check this box and then restart your MAMP. At this point you can now test your connection to MySQL with telnet or a node.js script.

Hint

Remember you can check which port your MySQL is running on by opening MAMP and clicking the ports link on the left navigation panel.

Mac OS on M1 MacBook Pro here with MySQL installation via brew:

Changing the host from ‘localhost’ to ‘127.0.0.1’ and creating a different user with a password solved this issue for me.
For some reason I cannot connect to my DB with root user and no password.
I created the new user on MySQL Workbench, but you can create a new user with admin privileges via the mysql CLI also.
Just google it.

This is how my backend looks:

const express = require('express');
const mysql = require('mysql');
const app = express();
const port = 3500;

const db = mysql.createConnection({
    host: '127.0.0.1',
    user: 'admin',
    password: 'admin',
});
db.connect((err) => {
    if (err) throw err;
    console.log('connected to database');
});

app.listen(port, () => {
    console.log('server listening on port 3500');
});

For some very odd reason, my computer only allowed me to have port 3306 as default port for my connection in order for it to work.

I wanted to comment my solution here, just in case there were people as newbie as me in databases.

I was getting this error because I had installed the mysql NPM package correctly but I hadn’t installed any implementation of MySQL on my computer (I didn’t know I had to).

I’m using Arch Linux so, in my case, with the NPM package already installed in my project, I did pacman -Syu mariadb (MariaDB is the default implementation of MySQL in Arch Linux) and then configured it following the guide.

Then, you can use the root user you just configured or create a new one to use in your project. For the latter:

  • Enter mysql CLI by running mysql -u root -p.

  • Enter the password for root user.

  • Create a new database with CREATE DATABASE mydatabase;.

  • Create a new user with CREATE USER test IDENTIFIED BY "testpass";.

  • Grant privileges to test user to use your new database with GRANT ALL PRIVILEGES ON mydatabase.* TO test@localhost IDENTIFIED BY "testpass";. See for more information on this.

And then, in my project, I would have:

let connection = mysql.createConnection({
    host: "localhost",
    user: "test",
    password: "testpass",
    database: "mydatabase"
});

If you are using MAMP please note that mysql default db_port is set to 8889 so you for this purpose I had to change it to 3306 (or whatever your app mysql db_port is set to).

My issue was that node server was connecting using port 3306, so it was giving the error below then crashing but mysql was up and seemed to establishing a connection through localhost, although I couldnt test it because node server was down.

errno: -61,
code: ‘ECONNREFUSED’,
syscall: ‘connect’,
address: ‘127.0.0.1’,
port: 3306,
fatal: true

Once I changed the port on MAMP mysql from 8889 to 3306, node server established connection through port 3000 and giving the statement below:

server running on port 3000
The solution is: 2

I use Windows 10 and I have Windows Subsystem For Linux (WSFL). I can execute my project from the WSFL console, but my MySQL is installed in Windows and they can not connect, however when I execute my project from a Windows console then it works without any problems.

You will encounter various kinds of errors while developing Node.js
applications, but most can be avoided or easily mitigated with the right coding
practices. However, most of the information to fix these problems are currently
scattered across various GitHub issues and forum posts which could lead to
spending more time than necessary when seeking solutions.

Therefore, we’ve compiled this list of 15 common Node.js errors along with one
or more strategies to follow to fix each one. While this is not a comprehensive
list of all the errors you can encounter when developing Node.js applications,
it should help you understand why some of these common errors occur and feasible
solutions to avoid future recurrence.

🔭 Want to centralize and monitor your Node.js error logs?

Head over to Logtail and start ingesting your logs in 5 minutes.

1. ECONNRESET

ECONNRESET is a common exception that occurs when the TCP connection to
another server is closed abruptly, usually before a response is received. It can
be emitted when you attempt a request through a TCP connection that has already
been closed or when the connection is closed before a response is received
(perhaps in case of a timeout). This exception will usually
look like the following depending on your version of Node.js:

Error: socket hang up
    at connResetException (node:internal/errors:691:14)
    at Socket.socketOnEnd (node:_http_client:466:23)
    at Socket.emit (node:events:532:35)
    at endReadableNT (node:internal/streams/readable:1346:12)
    at processTicksAndRejections (node:internal/process/task_queues:83:21) {
  code: 'ECONNRESET'
}

If this exception occurs when making a request to another server, you should
catch it and decide how to handle it. For example, you can retry the request
immediately, or queue it for later. You can also investigate your timeout
settings if you’d like to wait longer for the request to be
completed.

On the other hand, if it is caused by a client deliberately closing an
unfulfilled request to your server, then you don’t need to do anything except
end the connection (res.end()), and stop any operations performed in
generating a response. You can detect if a client socket was destroyed through
the following:

app.get("/", (req, res) => {
  // listen for the 'close' event on the request
  req.on("close", () => {
    console.log("closed connection");
  });

  console.log(res.socket.destroyed); // true if socket is closed
});

2. ENOTFOUND

The ENOTFOUND exception occurs in Node.js when a connection cannot be
established to some host due to a DNS error. This usually occurs due to an
incorrect host value, or when localhost is not mapped correctly to
127.0.0.1. It can also occur when a domain goes down or no longer exists.
Here’s an example of how the error often appears in the Node.js console:

Error: getaddrinfo ENOTFOUND http://localhost
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:71:26) {
  errno: -3008,
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'http://localhost'
}

If you get this error in your Node.js application or while running a script, you
can try the following strategies to fix it:

Check the domain name

First, ensure that you didn’t make a typo while entering the domain name. You
can also use a tool like DNS Checker to confirm that
the domain is resolving successfully in your location or region.

Check the host value

If you’re using http.request() or https.request() methods from the standard
library, ensure that the host value in the options object contains only the
domain name or IP address of the server. It shouldn’t contain the protocol,
port, or request path (use the protocol, port, and path properties for
those values respectively).

// don't do this
const options = {
  host: 'http://example.com/path/to/resource',
};

// do this instead
const options = {
  host: 'example.com',
  path: '/path/to/resource',
};

http.request(options, (res) => {});

Check your localhost mapping

If you’re trying to connect to localhost, and the ENOTFOUND error is thrown,
it may mean that the localhost is missing in your hosts file. On Linux and
macOS, ensure that your /etc/hosts file contains the following entry:

You may need to flush your DNS cache afterward:

sudo killall -HUP mDNSResponder # macOS

On Linux, clearing the DNS cache depends on the distribution and caching service
in use. Therefore, do investigate the appropriate command to run on your system.

3. ETIMEDOUT

The ETIMEDOUT error is thrown by the Node.js runtime when a connection or HTTP
request is not closed properly after some time. You might encounter this error
from time to time if you configured a timeout on your
outgoing HTTP requests. The general solution to this issue is to catch the error
and repeat the request, preferably using an
exponential backoff
strategy so that a waiting period is added between subsequent retries until the
request eventually succeeds, or the maximum amount of retries is reached. If you
encounter this error frequently, try to investigate your request timeout
settings and choose a more appropriate value for the endpoint
if possible.

4. ECONNREFUSED

The ECONNREFUSED error is produced when a request is made to an endpoint but a
connection could not be established because the specified address wasn’t
reachable. This is usually caused by an inactive target service. For example,
the error below resulted from attempting to connect to http://localhost:8000
when no program is listening at that endpoint.

Error: connect ECONNREFUSED 127.0.0.1:8000
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1157:16)
Emitted 'error' event on ClientRequest instance at:
    at Socket.socketErrorListener (node:_http_client:442:9)
    at Socket.emit (node:events:526:28)
    at emitErrorNT (node:internal/streams/destroy:157:8)
    at emitErrorCloseNT (node:internal/streams/destroy:122:3)
    at processTicksAndRejections (node:internal/process/task_queues:83:21) {
  errno: -111,
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: '127.0.0.1',
  port: 8000
}

The fix for this problem is to ensure that the target service is active and
accepting connections at the specified endpoint.

5. ERRADDRINUSE

This error is commonly encountered when starting or restarting a web server. It
indicates that the server is attempting to listen for connections at a port that
is already occupied by some other application.

Error: listen EADDRINUSE: address already in use :::3001
    at Server.setupListenHandle [as _listen2] (node:net:1330:16)
    at listenInCluster (node:net:1378:12)
    at Server.listen (node:net:1465:7)
    at Function.listen (/home/ayo/dev/demo/node_modules/express/lib/application.js:618:24)
    at Object.<anonymous> (/home/ayo/dev/demo/main.js:16:18)
    at Module._compile (node:internal/modules/cjs/loader:1103:14)
    at Object.Module._extensions..js (node:internal/modules/cjs/loader:1157:10)
    at Module.load (node:internal/modules/cjs/loader:981:32)
    at Function.Module._load (node:internal/modules/cjs/loader:822:12)
    at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:77:12)
Emitted 'error' event on Server instance at:
    at emitErrorNT (node:net:1357:8)
    at processTicksAndRejections (node:internal/process/task_queues:83:21) {
  code: 'EADDRINUSE',
  errno: -98,
  syscall: 'listen',
  address: '::',
  port: 3001
}

The easiest fix for this error would be to configure your application to listen
on a different port (preferably by updating an environmental variable). However,
if you need that specific port that is in use, you can find out the process ID
of the application using it through the command below:

COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
node    2902  ayo   19u  IPv6 781904      0t0  TCP *:3001 (LISTEN)

Afterward, kill the process by passing the PID value to the kill command:

After running the command above, the application will be forcefully closed
freeing up the desired port for your intended use.

6. EADDRNOTAVAIL

This error is similar to EADDRINUSE because it results from trying to run a
Node.js server at a specific port. It usually indicates a configuration issue
with your IP address, such as when you try to bind your server to a static IP:

const express = require('express');
const app = express();

const server = app.listen(3000, '192.168.0.101', function () {
  console.log('server listening at port 3000......');
});
Error: listen EADDRNOTAVAIL: address not available 192.168.0.101:3000
    at Server.setupListenHandle [as _listen2] (node:net:1313:21)
    at listenInCluster (node:net:1378:12)
    at doListen (node:net:1516:7)
    at processTicksAndRejections (node:internal/process/task_queues:84:21)
Emitted 'error' event on Server instance at:
    at emitErrorNT (node:net:1357:8)
    at processTicksAndRejections (node:internal/process/task_queues:83:21) {
  code: 'EADDRNOTAVAIL',
  errno: -99,
  syscall: 'listen',
  address: '192.168.0.101',
  port: 3000
}

To resolve this issue, ensure that you have the right IP address (it may
sometimes change), or you can bind to any or all IPs by using 0.0.0.0 as shown
below:

var server = app.listen(3000, '0.0.0.0', function () {
  console.log('server listening at port 3000......');
});

7. ECONNABORTED

The ECONNABORTED exception is thrown when an active network connection is
aborted by the server before reading from the request body or writing to the
response body has completed. The example below demonstrates how this problem can
occur in a Node.js program:

const express = require('express');
const app = express();
const path = require('path');

app.get('/', function (req, res, next) {
  res.sendFile(path.join(__dirname, 'new.txt'), null, (err) => {
    console.log(err);
  });
  res.end();
});

const server = app.listen(3000, () => {
  console.log('server listening at port 3001......');
});
Error: Request aborted
    at onaborted (/home/ayo/dev/demo/node_modules/express/lib/response.js:1030:15)
    at Immediate._onImmediate (/home/ayo/dev/demo/node_modules/express/lib/response.js:1072:9)
    at processImmediate (node:internal/timers:466:21) {
  code: 'ECONNABORTED'
}

The problem here is that res.end() was called prematurely before
res.sendFile() has had a chance to complete due to the asynchronous nature of
the method. The solution here is to move res.end() into sendFile()‘s
callback function:

app.get('/', function (req, res, next) {
  res.sendFile(path.join(__dirname, 'new.txt'), null, (err) => {
    console.log(err);
    res.end();
  });
});

8. EHOSTUNREACH

An EHOSTUNREACH exception indicates that a TCP connection failed because the
underlying protocol software found no route to the network or host. It can also
be triggered when traffic is blocked by a firewall or in response to information
received by intermediate gateways or switching nodes. If you encounter this
error, you may need to check your operating system’s routing tables or firewall
setup to fix the problem.

9. EAI_AGAIN

Node.js throws an EAI_AGAIN error when a temporary failure in domain name
resolution occurs. A DNS lookup timeout that usually indicates a problem with
your network connection or your proxy settings. You can get this error when
trying to install an npm package:

npm ERR! code EAI_AGAIN
npm ERR! syscall getaddrinfo
npm ERR! errno EAI_AGAIN
npm ERR! request to https://registry.npmjs.org/nestjs failed, reason: getaddrinfo EAI_AGAIN registry.npmjs.org

If you’ve determined that your internet connection is working correctly, then
you should investigate your DNS resolver settings (/etc/resolv.conf) or your
/etc/hosts file to ensure it is set up correctly.

10. ENOENT

This error is a straightforward one. It means «Error No Entity» and is raised
when a specified path (file or directory) does not exist in the filesystem. It
is most commonly encountered when performing an operation with the fs module
or running a script that expects a specific directory structure.

fs.open('non-existent-file.txt', (err, fd) => {
  if (err) {
    console.log(err);
  }
});
[Error: ENOENT: no such file or directory, open 'non-existent-file.txt'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'open',
  path: 'non-existent-file.txt'
}

To fix this error, you either need to create the expected directory structure or
change the path so that the script looks in the correct directory.

11. EISDIR

If you encounter this error, the operation that raised it expected a file
argument but was provided with a directory.

// config is actually a directory
fs.readFile('config', (err, data) => {
  if (err) throw err;
  console.log(data);
});
[Error: EISDIR: illegal operation on a directory, read] {
  errno: -21,
  code: 'EISDIR',
  syscall: 'read'
}

Fixing this error involves correcting the provided path so that it leads to a
file instead.

12. ENOTDIR

This error is the inverse of EISDIR. It means a file argument was supplied
where a directory was expected. To avoid this error, ensure that the provided
path leads to a directory and not a file.

fs.opendir('/etc/passwd', (err, _dir) => {
  if (err) throw err;
});
[Error: ENOTDIR: not a directory, opendir '/etc/passwd'] {
  errno: -20,
  code: 'ENOTDIR',
  syscall: 'opendir',
  path: '/etc/passwd'
}

13. EACCES

The EACCES error is often encountered when trying to access a file in a way
that is forbidden by its access permissions. You may also encounter this error
when you’re trying to install a global NPM package (depending on how you
installed Node.js and npm), or when you try to run a server on a port lower
than 1024.

fs.readFile('/etc/sudoers', (err, data) => {
  if (err) throw err;
  console.log(data);
});
[Error: EACCES: permission denied, open '/etc/sudoers'] {
  errno: -13,
  code: 'EACCES',
  syscall: 'open',
  path: '/etc/sudoers'
}

Essentially, this error indicates that the user executing the script does not
have the required permission to access a resource. A quick fix is to prefix the
script execution command with sudo so that it is executed as root, but this is
a bad idea
for security reasons.

The correct fix for this error is to give the user executing the script the
required permissions to access the resource through the chown command on Linux
in the case of a file or directory.

sudo chown -R $(whoami) /path/to/directory

If you encounter an EACCES error when trying to listen on a port lower than
1024, you can use a higher port and set up port forwarding through iptables.
The following command forwards HTTP traffic going to port 80 to port 8080
(assuming your application is listening on port 8080):

sudo iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080

If you encounter EACCES errors when trying to install a global npm package,
it usually means that you installed the Node.js and npm versions found in your
system’s repositories. The recommended course of action is to uninstall those
versions and reinstall them through a Node environment manager like
NVM or Volta.

14. EEXIST

The EEXIST error is another filesystem error that is encountered whenever a
file or directory exists, but the attempted operation requires it not to exist.
For example, you will see this error when you attempt to create a directory that
already exists as shown below:

const fs = require('fs');

fs.mkdirSync('temp', (err) => {
  if (err) throw err;
});
Error: EEXIST: file already exists, mkdir 'temp'
    at Object.mkdirSync (node:fs:1349:3)
    at Object.<anonymous> (/home/ayo/dev/demo/main.js:3:4)
    at Module._compile (node:internal/modules/cjs/loader:1099:14)
    at Object.Module._extensions..js (node:internal/modules/cjs/loader:1153:10)
    at Module.load (node:internal/modules/cjs/loader:975:32)
    at Function.Module._load (node:internal/modules/cjs/loader:822:12)
    at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:77:12)
    at node:internal/main/run_main_module:17:47 {
  errno: -17,
  syscall: 'mkdir',
  code: 'EEXIST',
  path: 'temp'
}

The solution here is to check if the path exists through fs.existsSync()
before attempting to create it:

const fs = require('fs');

if (!fs.existsSync('temp')) {
  fs.mkdirSync('temp', (err) => {
    if (err) throw err;
  });
}

15. EPERM

The EPERM error may be encountered in various scenarios, usually when
installing an npm package. It indicates that the operation being carried out
could not be completed due to permission issues. This error often indicates that
a write was attempted to a file that is in a read-only state although you may
sometimes encounter an EACCES error instead.

Here are some possible fixes you can try if you run into this problem:

  1. Close all instances of your editor before rerunning the command (maybe some
    files were locked by the editor).
  2. Clean the npm cache with npm cache clean --force.
  3. Close or disable your Anti-virus software if have one.
  4. If you have a development server running, stop it before executing the
    installation command once again.
  5. Use the --force option as in npm install --force.
  6. Remove your node_modules folder with rm -rf node_modules and install them
    once again with npm install.

Cover image for Node.js Error: connect ECONNREFUSED - how to connect Node with phpMyAdmin

I spend more than 6 hours searching and testing, I get frustrated, angry and you know… just for 3 minutes job.

Here it’s my success story with incredible persistant Node.js error connect ECONNREFUSED .

Day 1.
I run this code, and should work fine.
Node Connection

Oh, but no, some errors
Error: connect ECONNREFUSED

Usual errors, maybe 3-4 minutes. I changed host: ‘localhost’ to host : ‘127.0.0.1’, port: 8080, or maybe 8000, oh yes, 3306 this is. No, not that. Oh, yes, hostname: ‘127.0.0.1:3306’. No. Adding database, remove database. Change every thing I can now change. Nothing.

«You should check if your XAMMP server is running», yes it is green.
Error: connect ECONNREFUSED

Maybe it is the port 8443. node app.js enter, connect ECONNREFUSED. no, it’s not the port. No password, no root, no port. What can solve this?

OOhh, yes, I know, I should thinking about that. Maybe I need to put the project in root XAMPP root folder. No.

connect ECONNREFUSED

3 hours later. I need more music.

Day 2
Today, Sunday, with some first snow outside, I discovered something new. There is an IP address on my XAMPP, and maybe this is how I can solve the error.
Error: connect ECONNREFUSED

Unfortunately it was not the case.

Starting to find the real solution in my case
And after I read Yannick Motton’s best answer on post host-xxx-xx-xxx-xxx-is-not-allowed-to-connect-to-this-mysql-server I found the solution.

The solution:

1. Create an user with password, and grant all provileges
CREATE USER ‘username’@’localhost’ IDENTIFIED BY ‘password’;
GRANT ALL PRIVILEGES ON . TO ‘username’@’localhost’ WITH GRANT OPTION;
CREATE USER ‘username’@’%’ IDENTIFIED BY ‘password’;
GRANT ALL PRIVILEGES ON . TO ‘username’@’%’ WITH GRANT OPTION;
FLUSH PRIVILEGES;
Error: connect ECONNREFUSED
This will set user: username and pass: password

2. Change localhost with your XAMPP IP (and also add username/password for user and password)
Error: connect ECONNREFUSED
Change host: «localhost» to host:»192.168.64.2″, and update with user: «username», password: «password».
node app + enter
Error: connect ECONNREFUSED
Connection established It’s done. Hooray.

3. Celebrate the victory
Now that your terminal print Connection established, you whould celebrate the victory with dev friends.
Error: connect ECONNREFUSED

Final thoughts

Hope this article will help you to solve the connect ECONNREFUSED error and to connect Node.js with phpMyAdmin in just a few minutes.

“Patience, persistence, and perspiration make an unbeatable combination for success.” — Napoleon Hill

I’m running into the same issue. Even if I try getting all my collections using the Postman API key (https://community.getpostman.com/t/where-do-you-see-your-own-uid-for-collection/3537) I generated I get a ‘connection refused’ response.

Request:

curl https://api.getpostman.com/collections?apikey=XXXXXXXXXXXXXXX/ -v

Response:
Failed to connect to api.getpostman.com port 443: Connection refused

It may be a proxy issue — I did try specifying the proxy IP address and port in Settings and all tried with and without ‘Use System Proxy
Enable this option to allow Postman to use the system’s default proxy configurations’.

I also tried to make the request outside the firewall — I get a more explicit error there:

‘AuthenticationError’.

I’ve copied the API key directly from the Postman Integrations, Existing API Keys page. It currently has a status of ‘Enabled’ and ‘Last Accessed’ of ‘Never Used’. ‘Date Created’ is June 7, 2019.

I’ve ran out of ideas for now. Any thoughts or suggestions are more than welcome!

Thanks for your time :)
