I have problems for a few days too. I receive always after loading the game:
Connection issue
Connection to the server has been lost. Please wait while we try to resolve this issue.
I tried with Chrome (Version 106.0.5249.119 (Offizieller Build) (64-Bit)) and with Firefox (106.0.1 (64-Bit)).
Last week I was able to play without any problems... I dont think that something on my PC changed.
