"verbindung mit einem odere mehreren konnte nicht möglich"

Something like, connection with one of the other accounts was not possible...

Also happens if I try to connect with an incorrect password. Maybe it is a reused error message so. Not that specific...

Any idea what that might cause? I also noticed that by using #@$, one of those not sure, it gives me the same error.

Tried to take a screenshot but I need to hold the camera button for 20 seconds and the popup disappears long before the 20 second time.
