Error "Could not connect to game"

Hi, I can not login to my main character. Other chars no problem.

Char Name : Ohame
Region : Eu Central / Sirius
Location : Throne of Chaos


They’ve just taken the servers down for Maintenance. I was connected and then there was a message that said “Maintenance 5m” etc etc. Maybe to fix the issues all those that were in instances had with logging in when the server crashed.
