Game version is whatever the latest game version is as I write this.

Can't join a single multiplayer server. Getting "Kick cause code: group=1 'REPLICATION', reason=3 'CONNECTION_FAILURE'" message or ""No connection with backend. The response from the server took too long. Check your network connection and try again."

Only bought the game on Thursday. Played an hour or so on Thursday night and it was fine. Joined a server earlier and played for 30 mins and was booted with a connection error of some kind and ever since been unable to join getting the above messages.

There is nothing wrong with my connection. I have tested it and have a full fibre 300Mb connection with an 8ms ping. Zero packet loss. Every other game works fine and all tests run on the connection come back clean.

There are zero mods installed as I just installed the game. Only played on official server.
