this happens when you try and log in when you're character is still classed as 'online' by the server.

e.g. after a crash / disconnect and you log back in right away.

You will also get a bunch of Error 307's after this one goes away


After around 3-5 mins it will tidy up after itself and let you log in again but trying before then tends to reset the timer.

I would consider this a bug personally, I don't think the game should be locking players out of their accounts if they mistakenly try to rejoin the game 'too fast' after a crash. It's really frustrating and also ruins a lot of players Cyrodiil experience, they queue for an hour then crash attending a large fight then experience this bug and by the time they log back in are back outside of cyrodiil.

It didn't used to be an issue a few years ago.
