Login Queues are almost totally drained again. If you have an obscenely long wait time atm, please try re-launching your client. (Edit - they are on their way to being totally drained. May still take 15-30 minutes to be totally drained, sorry for jumping the gun)
Today is the day of endless Fortnitemares for sure.
We are digging into a new issue with our login service - which is what folks are reporting as basically failing entirely to log in. Retrying may help. We are actively trying to resolve this atm.
We believe this may be secondary fallout from the flux of repeated logins due to the ongoing problems today and issues with sessions cleaning up as a result. We are working on this, sorry for the shenanigans one after the other.
