Hi

So I used to play this game quite a lot. I have 800+ hours on it. I really liked it till I got this issue. I used to have green nat and I was able to join matches

very quickly but I got problem with the router I had at the time, had to replace it with a new one. and after that, till this very moment I always had red nat ever

since. tried to open ports and check if they were actually opened using software and yes they were opened. tried multiple fixes but none of them worked.

now I'm literally unable to play the game. I would appreciate it if someone can help me.
