Been unable to login for a very long time...

It started as a Ban appeal - been told that disabling and enabling 2FA will fix it - it has fixed it for a week and then got another Ban appeal for no specific reason.

Coming back now to this server 2 years later finding out that nothing has changed...
Tried to set up my 2FA got a code - typed it in the dialog and nothing - generic message of can't log in.

Set up a google authenticator and now it won't even pop the dialog anymore...

Please help - getting very frustrated and don't wanna go to other private servers simply cause they aren't as good as this one...
