Disconnect during Maven Fights

Hello,

I have experienced mutliple sudden disconnects during fights in the Maven's Crucible. The game instantly sends me back to the login screen with no error message. Apptempting to reenter the arena disconnects to the login screen again.
This happens regardless of the character used and the type of Maven invitation.
A restart of the game does not help either.

This is from the client log:
