Submitted an inquiry about this issue. Depends on when do they reply now. P.S. another problem is that i'm needing to post twice or it doesn't appears some times
Based on what I can understand from the error log, it seems that something's wrong with their login server, or the client connection to it. If there are people still online, it seems it's just the login/authentication/whatever server that's having issues.
I've sent a bug report with the log. Hopefully it'll get fixed quickly enough.
