when i deploy a server it just stops doesnt even show the loading screen.

i tried with bots it opens without any problem but when it comes to online servers i cant even see the loading screen.
it just stops and stuck at the main menu. when i press esc it returns to main menu and i can disconnect or exit but i cant go back to game, it freezes again. i was a regular player 3 years ago now i got a new computer i wanted to play again but i couldnt. please help i love the game.

It is caused by some packets being blocked. Talk to your ISP.

I have the same error, I haven't played for about 3 years and a few months ago I tried to play it and this happens, until now. have you fixed it?
