The issues on the North American and European PC/Mac megaservers have been resolved at this time. If you continue to experience difficulties at login, please restart your client. Thank you for your patience!
Also getting "unexpected internal error" on both PC-NA and PC-EU. Tried restarting Steam a couple times, tried restarting my whole computer. Can't use the help.elderscrolls.com website because dark theme gives me a migraine (no this is not up for debate) and there's no reader mode setting.
I cant log in on my main account. Login failed. Username/ password may be incorrect or inactive try steam. I can however log in to my alt account. very strange.
