The error message "*Authentication failed - Invalid credentials*" means that the Android account manager was not able to refresh the access token.
|
|
|
|
|
|
|
|
A common cause for this problem is using a VPN, a firewall app or an ad blocker which blocks internet access for the Android account manager.

You can workaround this issue by using an app password.
