After further review we have decided to move this thread to a category we think is more appropriate for this topic, as it deals with PC troubleshooting.
Started happening today, tried all that you stated, as I did last time and no go. Last time it cleared up in about a week.
UK or NA same issue. PTS I can login to. I believe PTS is the cause. I quit it last time and issue cleared up.
Removed PTS, now I can log back into prod servers.
