I've tried almost everything and it keeps popping up with this. the other forums weren't helpful. It started doing this after I failed to login correctly the first time.
This could be a cache problem. Try to clear the borwser cache. Maybe it's automatically trying to log you in with the incorect password.
Alternatively/additionally, try going to the site in a private/incognito tab, then enter your credentials, then klick on "Kick" or "Kick & Resign", in case you are hanging.
