Disconnect in Dornogal

Hello,

I am getting disconnected from game 50% of the times i enter Dornogal via hearthstone. I then end up getting disconnected within 3 seconds of entering the world until i wait 15-20min. Sometimes i manage to use my Dalaran HS to escape this loop. This happens only on that specific character and I can without any problems at all enter the game and play on my other characters, even the ones in Dornogal.

I have updated my drivers, uninstalled addons, repaired and even done a complete reinstall of the game.

Does anyone know what is going on?

Are you getting DCed back to the log in screen or does the game fully close?.
Actualy, im wondering if you got a bugged quest on that character thats doing that..
