Same. Also eso launcher seems to work extra slow (it is stuck for like 1 minute "no response" and after that it gets un-stuck and I can hit "play" button). Was working fine yesterday and I had no system or driver or eso updates.
I think this happened before and what it seems like is happening is that the server is recognizing you as still being logged in when your client is telling you the opposite. It is frustrating and shouldn't be around but generally a 5-10 minute wait is an easy way to not have to deal with it.
This has been happening to me since late last year. It took me TWO DAYS just to get through the antiquities tutorial because I kept getting disconnected. Not fun to play anymore...
