log in problems and disconnects

Hi ggg
Major issues with the servers tonight, players are struggling to login and stay in the game when they do get in. When logging in various messages appear including...unable to connect to login server and another user has accessed your account. I managed to login to talk in global chat and many players experiencing same issues. We have been trying london realm and frankfurt realm.
Any loading screen can result in being returned to title screen and error message, an unknown error occurred then you struggle to login again.

Hopefully you can find a fix for this as it is gamebreaking

platform...xbox series x

Thank you
