- Temporary glitches.
- Unstable internet connection.
- Server issues.
- Corrupted cache.
- Outdated BGMI app.
How to fix the issue?
Here are seven methods that might help you resolve the server authentication error:
Restart the game and the device
Sometimes a simple restart can work wonders. Close BGMI completely, then restart the app. If the issue persists, give your phone a reboot as well.
Check your connection
Ensure that your WiFi is functioning correctly, or if you’re using mobile data, make sure you have a strong signal. Consider restarting your router or toggling Airplane mode on and off to refresh the connection if you encounter any issues.

Check the server status
In some cases, the server itself might be down for maintenance or experiencing technical difficulties. You can check online sources or BGMI’s official channels for server status updates and you can also use services like downdetector to check the status.
Repair the game
BGMI offers a built-in repair function. On the login page, look for a Repair option available usually on the right side. Running a repair can fix corrupted files that might be causing the login issue.
Clear BGMI app cache
Cached data can sometimes cause login problems. Try clearing the BGMI app’s cache. Be aware that this won’t delete your game progress, but it might remove any temporary files causing issues.

Update BGMI
If your BGMI app is not up-to-date, it may not work well with the latest server version. Check the Google Play Store to see if there are any updates available. If there are, download and install them to make sure your app is in sync with the servers.

Reinstall BGMI app
If none of the previous methods work, you might want to try reinstalling the game as a final option. Keep in mind that this will delete all your game data, so ensure that your account is linked to a social media platform to save your progress.
