i go to support, and he says me Please follow this guide, this will most likely fix your connection issue.
To change your client port:
Close CS:GO/Dota 2 -> Go to your Steam Library - > Select CS:GO/Dota 2 -> Right click on the game -> Properties -> Set launch options -> Copy and paste this --> +clientport 27006
(You can also replace the last number with 7-9 Default = 27005)
Now, start your game again and attempt to join your FACEIT server.
Unfortunately you won’t have time to connect, this is a client sided issue i’m afraid.
Change your port though, it will help fix the issue for future cases.
CAN U UNBAN ME? plz
