As players celebrate the release of the new mini-set inPokemon TCG Pocket, some are being locked out by an infamous error code that has persisted since the game’s global launch. Although it has never been this prominent, it now seems like one in every ten players is encountering anAuthentication Errorwhen trying to open packs or log into the game. On December 17, the devs issued an Update Notice addressing known issues with the Amber Trainer Card acquisition but did not mention the login error messages affecting players worldwide.
Don’t worry, though. The Authentication Errors inPokemon TCG Pocketcan be fixed—at least, they can be minimized. By following the instructions and workarounds in this guide, you’ll likely resolve this glitch entirely.
How to Fix the Authentication Error
TheAuthentication Error inPokemon Pocketdisplays the message: “The server authentication process failed. The game will now restart.” All you’re able to do is press the OK button to exit to the title screen. If this problem persists, follow these steps to fix it:
If you’re on iOS, you may need to uninstall and reinstall the game to remove its cache from your device. It’s also a good idea to restart your phone after the uninstallation is complete, just in case any system cache is causing the issue.
Android users can manually deletePokemon Pocket’s cache by going to:
Settings > Apps > Pokemon TCGP > Storage > Clear Cache.
EnsurePokemon Pocket is linked to your emailaddress or Nintendo account so you don’t lose any progression or data.
How to Fix Error Code 102
Error Code 102 simply says, “An error has occurred,” leaving you with two options: Retry and To Title Screen. Pressing “To Title Screen” seems to send you into an error loop, repeatedly showing the same message and causing the game to get stuck. However,tapping the “Retry” button will temporarily fix the error.
Since this issue was likely caused bythe recent Mythical Island update, it will likely require a hotfix from the developers. In the meantime, there are several things you’re able to do to avoid encountering Error Code 102.
Workarounds and Possible Fixes to Try
It’s worth noting that this error started appearing right afterthe release of the Mythical Island expansion. This suggests thatPokemon Pocket’s servers might be overwhelmed with millions of players logging in simultaneously to open booster packs. Hopefully, as the update settles and server traffic normalizes, the error will affect fewer players.
