Error 90k on 1 character only

[Mhyrria]

As title say, I receive error 90000 only on my main character. I was playing fine hours ago, then decided to logout to have dinner. I came back and receive the error 90000. I logged in to another character on the same server with no problems. I logged in on another character in Behemoth with no problems as well. I tried multiple times logging in to my main, but receive 90k error for all occasions. What gives?

And now it magically connects. O.O
