Question VAC Authentication Error Fix!

[macrow7]

My friend always played cs: go without any kind of mistake. But recently, he has had an error called (VAC Authentication Error) and he does not know how to solve. If anyone has a solution, please comment below because it is impossible to play with him and we are always losing games.

Is your friend hacking, by chance? That'll do it.

No he isn't.

However, VAC's aren't issued by mistake very often. If your "friend" even experimented one time with a cheat, and got caught, then he's permanently removed himself from that game.
