Cant connection to some player in lobby

When i join to random lobby i dont have connect to some other players but only some, not all (this is can be with all player's not only which RU)( image url)

@pe6yx But if i create lobby i dont have this problem and all player's can connect to me even those who didn’t have a connection with me, also if I go to the lobby where there will be one host, then all the players who come after me have a connection without any problems, it problem started after the last update.

some more proofs about ("this is can be with all player's not only which RU") here we can look i have connect with two RU player but dont have with UA, two RU, and some dude (srry dont know this banner)

For testing purpose, disable any security software/firewall. I would guess the firewall is interfering with the patched files, when it has worked before.

I think it is flag of Cyprus? Not sure about that, hard to see in the image.
