CS2 Valve Anti-Cheat challenge timed out
I'm getting kicked out of matches after a few rounds and I get the following messages in succession:


You cannot play on secure servers for one of the following reasons
An issue with your computer is blocking the VAC system.
You are unable to maintain a stable connection to the VAC system.
You are running software that is modifying the game or is incompatible with VAC.

yes, glad i am not the only one. just happened to me 20 min ago and took a good 15min to get back in. I restarted everything 3 times before i was able to get into a match.

i had this EXACT issue back in 2015/2016 .. i was on constant 7 day cooldown, after sending like 10 support tickets and NO fix, i gave up and uninstalled. only got back into cs2 about 5-6 months ago.

i had this issue on win 7, i even went to win 10 and still had the issue.
as a PC expert i tried every possible thing i could think of, nothing worked.

it started happening after csgo update. everyone in match, including my friend, got kicked. then there was small csgo update and i couldn't reconnect.
my friend rebooted pc and got back in, i didnt.

then it started doing it at random, it was 50/50 chance. sometimes it worked fine, sometimes it kept kicking me and wouldn't let me rejoin either.

This just occurred to me after this new update. Any fix?

[Ace001]

same for me. tried verifying file integrity and restarting PC - it goes away for 30 mins or so and then back to VAC time out. Any fix?

Try reparing steam and game files and windows files, update all te drivers, remove trash apps you dont need.

windows repair commands:
Chkdsk c: (and game default ssd)
sfc /scannow
DISM.exe /Online /Cleanup-image /Restorehealth

Steam repair commands:
Solution 1: Verify Integrity of Game Files
Solution 2: cmd/adm \Steam\bin\SteamService.exe” /repair”

EX: if u run cs as administrator u need to run steam also as administrator, otherwise get into conflict. If u run cs as not administrator than run steam as non administrator. Hope it helps
