Error 5003 and subsequent Authentication Errors

[Ironman2ooo]

I just tried to log into the game (Windows ver) and got disconnected with a 5003 authentication error while I was in the queue. Since then, when I go to log in, the launcher states there's been an authentication error and I cannot even go past the launcher.

I was in que, went from 4500 to 1700 and got disconnected with the 5003 error and now when I try to sign in, I keep getting this over and over now
