Steam Anti Cheat Servers are not responding

I’ve been looking for a solution. i have about almost 2500 hours on unturned and i’ve never seen this. whenever i join a server it will stop for about a second and then move me to a screen that says steam anti cheat servers are not responding. i’ve looked up videos and i’ve tried reinstalling battleeye, and validating my files. nothing works. someone please do something about this.

Restart steam. Usually this fixes this sorta error.
