Authorization failed to complete within the timeout limit

Hello.
Recently I have been unable to connect to any server. When I try to connect after a while a message appears - Authorization failed to complete within the timeout limit.
I reinstalled the game. After installing patch 1.7, I was able to connect to the server, but a message appeared that I should update to СODx. As soon as I updated to 21.1 I again cannot connect to the server with the same problem that I described at the beginning.
Any suggestions?
