Can't log in to character

Hi there,

I play on WoTLK in the Ice Crown server - recently I was in an Ulduar 10 raid on my death knight, Laynelas, and logged out without leaving the instance. Now whenever I try to log in to my character, it fails and shows a a "Login failed" message. I tried using character unstuck which did not work. Any ideas why that is, or how I can go about fixing it?

Server restart should fix it. But you can also try making a support ticket in game from another character.
