Tachiyomi ошибка 404

Tachiyomi is one of those few apps in which you can read the manga. In case you do not know, the manga is called the collection of Japanese anime content. Earlier, this manga referred only to comics, magazines, etc. But as per the modern standards, the same refers to animation, movies, cartoons, and more. Now, Tachiyomi offers you with an ad-free and huge library of such manga. Also, it is rare to find such an amazing app with regional or specific focused content.

Now, Tachiyomi also comes with some set of features which definitely make it stand out. Some of them include extensions, labels, categories, downloads, tracking, and more. Also, you can download Tachiyomi on both Google Play Store and APKs for free. In case you want to get it on Windows or Mac, then check this out.

All in all, Tachiyomi is a good and well-rounded app for manga readers. But as with every other app or service, it comes with a set of errors at times. So, here are a few such common errors along with the method to fix them out. With that out of the way, let’s begin.

Tachiyomi errors download, 5oo, 403, 404, etc.

Downloading error: 

First of all, let us address the errors that you see whil downloading any manga. Also, it is mostly common and thus are the methods to fix it. All you need to do is restart the application and check for the network connectivity. Also, you can try to clear the cache of the app, force stop it and even reinstall the app altogether. If that does not work, then you can try to download another manga as well.

Error 500: 

In many cases, the problem does not persist on the user side. It is highly likely that the server itself is down. In this scenario, no matter whatever you try to do and figure out, the error stays in. So, the best possible solution for this error is to source in Webview. To do this, first select the manga or comic you want to read. In this section, click on the three dots menu on top right corner and select Open in WebView. Lastly, verify the captcha and see if that resolves the error.

Error 403: 

Just like the above one, error 403 also carries a similar approach. Indeed, one of the methods to fix this error is to follow the above steps as mentioned. In many cases, it should work fine. But if the problem lies in WebView, then you need to install or update Android System WebView. This can be done in the Google Play Store.

Error 404: 

Tachiyomi aside, error 404 is infamous for the message Server not found. So, the same is the case with Tachiyomi here. Now, whenever Tachiyomi throws error 404 then it is sure that the content you want to access is not available. So, the best way to deal with this error is to cross check the availability.

Conclusion: 

In short, these methods should work in most of the cases. So, make sure to follow these steps and fix those annoying errors. On a side note, you can also check the official community and get more solutions here. Lastly, share this with your friends and others who also use Tachiyomi and may face the similar sort of errors.

Possible reasons: your internet connection is bad, the app doesn’t have access to the internet, your ISP have blocked the site, the site is down. Try using different internet connection (switch to Wi-Fi, mobile data or a VPN). Try to enable more_horizMore → settingsSettings → codeAdvanced → DNS over HTTPS.

java.security.cert.CertPathValidatorException / Chain validation failed

java.security.cert.CertPathValidatorException or Chain validation failed means there is a problem with validating source’s sertificate.

• Check if the site’s certificate have expired. Use an online service for checking SSL certificates. If the certificate have expired, then wait while the site owner will renew it.

Attempt to invoke virtual method ‘com.hippo.unifile…

Attempt to invoke virtual method ‘com.hippo.unifile… error can be caused by a variety of reasons, all to do with storage.

• Most commonly it is caused by full storage, check to see if your device or SD Card is full.
• Check if Tachiyomi has access to the SD card. You can enable it in the android settings for app permissions.
• If you’re downloading and this error pops up, that means the app might not be able to access the folder you’re trying to download to. This may be because the folder is corrupted or does not exist. Use a file manager to check that the folder(s) exist and every folder in the sequence is available and accessible.
• The drive you’re writing to is corrupted. Check using a file manager to see if it is accessible.

Cannot Access SD Card

Cannot Access SD Card error is typically caused by having a file or folder name that is too long. Android’s file manager does not support filenames longer than 255 characters. If you know the file or folder name that is the culprit, you can connect your SD card to your computer and shorten it. Otherwise, delete the Tachiyomi downloads folder off of the SD Card.

Diagnosis

• Verify your extensions are up to date (exploreBrowse → Extensions, make sure no extensions have an Update button).
• Check if Tachiyomi has an update (more_horizMore → infoAbout then click Check for updates).
• Verify that WebView is updated.
• Try opening the manga in publicWebView. If there is a Cloudflare protection, wait for it to load. If there is a CAPTCHA, solve it and see if it helped.
• Change your internet connection (switch to Wi-Fi, mobile data or a VPN, use a «What’s my IP» site to confirm your IP has changed), then try again.
• Ask other users to try the action that gives you the error.
• Check if the source is either down, or is having issues in a browser.
• Press the retry button in the middle of your manga page if one exists.
• Try the following at more_horizMore → settingsSettings → codeAdvanced
  • Clear Cache
  • Clear Cookies
  • Clear Database
  • DNS over HTTPS
• If your downloads are getting stuck, try deleting the queue and trying again.
• Force close Tachiyomi and reopen it.

Your issue may have been fixed in the Preview version already, just wait for a new Stable release.

If any of these help, go to it only happens to me.
If it’s not just you, go to everyone is having this problem.

If none of these help, try asking in our Discord Server. State app version, source, manga and chapter with the problem.

It only happens to me

You may be getting a Cloudflare protection, may have been IP-banned, or encountered some other counter-measure that website owners deploy against programs like Tachiyomi. If that is the case, there is probably nothing that can be done about that. Some of them (like Cloudflare) have to be manually solved, some are temporary (IP bans).

Workarounds that can lower chance of it happening again:

• Don’t use downloads with the source.
• Have less manga in library from the source.

All of the above are very imprecise and fuzzy rules, because each site has their own, non-public limits and triggers.

Everyone is having this problem

If the site is reachable and fully functional then there may be an issue with the extension or app.
1. Have a look at open issues for the app and/or extensions.
1. It may have been fixed already, but not released yet, so look at closed issues (app / extensions) issues as well.
1. If you can’t find the issue there, open a new one.

If the site is not reachable or having issues then all you can do is wait for the site to become functional again.

Solving the Cloudflare issue

Please note that WebView is not the same as using your browser.

You must solve the Cloudflare issue in WebView.

Update WebView

To update WebView, you need to find what WebView implementation is used on your device. In general, default implementation depends on the Android version as follows:

• Android 10.0 and higher — Android System WebView.
• Android from 7.0 to 9.0 — Google Chrome.
• Android 6.0.1 and lower — Android System WebView.

Users of Android 7.0 and higher can also see and change WebView implementation in Developer Options.

Non-standard implementations like Firefox can lead to Tachiyomi not working correctly or in the worst-case crash. We recommend to set WebView implementation to Android System WebView or Google Chrome.

# Solving Cloudflare issues

Cloudflare is an anti-bot mechanism. Some sources intentionally have a higher Cloudflare protection level to block apps like Tachiyomi. You can try the following suggestions to help resolve Cloudflare challenges. If they don’t work, migrate to other sources or wait until they lower their protection.

# Loading the website in WebView

Try to load the website in WebView. Note that WebView is not the same as using your browser.

You may need to try this multiple times. You can also try pressing the

more_vert

Overflow icon, opening the website in your regular browser, then checking for a CAPTCHA there.

Some sources may have more advanced Cloudflare protection. If you are facing issues, try the following options.

# Clearing WebView data

# Changing your user agent

A user agent string helps websites identify information about the requester. While some sources have user agent strings set, most rely on the default value set in the app.

# Update WebView

To update WebView, you need to find what WebView implementation is used on your device. In general, default implementation depends on the Android version as follows:

• Android 10.0 and up — Android System WebView (opens new window).
• Android from 7.0 to 9.0 — Google Chrome (opens new window).
• Android 6.0.1 and below — Android System WebView (opens new window).

# Unable to install the app or extensions

Try installing Split APK Installer (opens new window) from the Google Play Store, then use it to try and install the affected APK. Split APK Installer will tell you why the APK is uninstallable, or it will install the APK for you. Some common errors are listed below.
