I have a 4g broadband connection on the Three network in the UK and I can no longer connect to any server.

I have tried validating, reinstalling, running as admin, disabling mods etc.

The game will load, I can play in "offline mode" and it runs fine. I have even managed to get into a server once in about 100 tries.

As soon as I try to load into any server, the game will come to the loading screen and get about halfway before the game hangs. You can tell that the game is trying to connect but nothing happens. It just stays like that for a couple of minutes before the server kicks me as I have timed out. The error then says authplayerloginstate.

I have even tried switching router, however still on 4g, it doesn't make any difference. This is the only game that has this problem, ping is only 50 to UK and France, I have no VPN.

I am not sure if Three 4g IP addresses are somehow blocked from playing.

I can no longer play the game.
