How do i know if someone got ip banned

[lordkermitty]

So my friend cant connect to the game or the website so i was asking if he was banned because i can still log into his account and play his characters

Tell him to try deleting DNS cache. After that to restart his router.
Did this start recently, could he log in before normally?

Actually now he can go on the website, yes he could log in normally before
