Server has closed your connection

[Coar]

Hi i playing Warhammer now a few Months without Problems. In the last 2 Weeks(maybe more) i get very frequently the Message "The Server has closed your connection;you has been disconnected" when logging in a Char ( im maybe aware only my level 40s, could be a coincidence ). It happens when i start the game or when changing from one toone to another and it showing me the "loading screen" for a long time before the message. When i try to log in the same over and over it still happen, sometimes it fixxes it when logging in a low toon , then my 40s after.

I try to:

Close the game and delete the Temp Folder and use the Repair Function of the Launcher. Multiple times without any change.
My Guildnote is only 3 words, we got 330ish members.

What else can i try?

Pls help its realy frustrating
