Whenever I try to join a multiplayer game, I am kicked after being in the lobby for 5 sec. It happens on every server, I have tried. I am using no mods, and during server browsing all the servers are shown available (green) to me. Even If I choose a class quickly and start downloading the mission files, I am kicked during that process too.

I had no problems on older versions, I could play on every server, but since the last update there is no more multiplayer for me.
