Well, duh. It's an MMO. What did you expect?
It took a while for the console version of The Elder Scrolls Online to reach PlayStation 4 and Xbox One and now that it's here, players across North America and Europe are reporting login issues.
The complaints are showing up at NeoGAF and the game's official forums . Bethesda has responded, saying on Twitter that they're working on the problem. They also offer a possible workaround for the "Login Failed" error.
Personally, I have no idea how people can stand this constant instability. If you go by the news, it seems like MMOs never work when they first launch.
