Common Problems
I receive an error attempting to use the old Authenticator app.
I get Error 502 Bad Gateway
The Battle.net Authenticator is now available in the Battle.net Mobile App, if you had previously setup your authenticator using the old app, then removed the app. You will need to remove the current authenticator from your account.
If you're having trouble completing the set up of a new Authenticator:
- Close any apps running in the background
- Check your device's internet connection
- Make sure you have enough free space on your device
- Try removing and reattaching your Authenticator
- Uninstall the app, restart your phone, then reinstall the Authenticator
- Clear the Authenticator's Data and Cache from your device's app manager, restart the app, and try again
