How to Fix the Tachiyomi Failed to Get Extension List Error
If you are encountering the “Tachiyomi failed to get extension list” error then you can fix it by using the methods mentioned below.
Check Your Internet Connection
Tachiyomi is an online application that requires a stable and fast internet connection to work properly.
If there is an issue with your internet connection then it must be the reason why you are encountering this error.
In that case, you should check your internet connection and make sure to have a fast and stable internet.
The best way to check your internet connection is by performing a speed test by using internet speed testers available on the internet.
Check Tachiyomi App Permissions
Another main reason why Tachiyomi can not find the extension list is restricted app permissions.
If the Tachiyomi app does not have the required permissions to access media and storage then you may encounter issues and errors.
In that situation, you should check the app permission and make sure to have all the required permissions.
Here is how you can check and provide the Tachiyomi app permissions on Android devices:

- Scroll down and select Apps.
- Then select Manage Apps.
- From the installed app list select Tachiyomi.
- Under app settings go to App Permissions.

- Here check and provide all required permissions.
- That’s it.
Update Tachiyomi App
If you are using the outdated version of the Tachiyomi app then it must be the reason why you are encountering this error.
In that case, you should try updating the Tachiyomi app and check if it fixes your problem.
Because Tachiyomi is not available on Google PlayStore you can install the updated version of the app from third-party websites.
To do that open your web browser and search for the Latest Version Of the Tachiyomi App.
This will show you multiple results, go to any trusted website and download the latest version of the app.
Clear Cache
Corrupted and outdated cache files also prevent the app from working properly.
If you have not cleared the Tachiyomi app cache files then you can fix the “Tachiyomi failed to get extension list” error by clearing the cache.
Here is how you can do so:
- Open Settings app.
- Navigate to Apps > Manage Apps.
- Here find the Tachiyomi app and select it.
- Now go to Storage.
- Select Clear Cache.

- That’s it.
Check If the Source Name Has Changed or the Server is Down
As I mentioned earlier, you might be encountering the “Tachiyomi failed to get extension list” error because the source from which you have downloaded the manga has changed the title.
In that case, you should check if the source has changed the name.
You can also try checking the server status. It may be possible that you are facing this error because the Tachiyomi server is down.
To check the current status of the server you should use the Downdetector website.
This online tool will show you the current status of the server based on the reports submitted by other users.
If you find any issue with the server then you have to wait until the issues in the server are fixed.
Enable NSWF Source 18+
If the NSWF Source 18+ option is disabled then it must be the reason why Tachiyomi is unable to access the extension list especially when the desired extension falls under the 18+ category.
In that case, you can fix this error by enabling the NSWF Sorce 18+ option. Here is how you can do it:
- Open your Tachiyomi application.
- Select More from the bottom right corner of the screen.
- Click “Settings” from the menu and click on “Browse”.
- Find the NSWF Source 18+ and enable “Show in Sorce List”.

- That’s it, restart your device and check if the error is fixed.
Make Sure the SD Card is Recognized
If you are using the SD card to store data make sure it is recognized.
To check it, open the File Manager and go to the storage section. Here check if the SD card is shown or not.
If the SD card is not showing then you can remove it and reinsert the SD card to check if it is recognized or not.
If the SD card is still not recognized then there is an issue with the card you should try using another SD card.
That’s it these are some troubleshooting methods you can use to fix the “Tachiyomi failed to get extension list” error.
