Error connecting to the lobby

In the morning I go into the game, I want to connect to the game, and it gives out this ...
I checked the game files through steam, reinstalled the faf, there are no mods. version 1.4.3

Are there any options for how to fix it?

Cut off the antivirus and the problem disappeared ...

Thats a classic
