Counter-Strike: Global Offensive (CS: GO) is a game loved by many players around the world. However, if you try to queue for matchmaking, you may receive a “VAC could not end your game session” error. Many online players have reported this error when trying to join the Steam Community or while playing.
If you’re looking for a solution to this problem, you’ve come to the right place. We will present several fixes with which you can try to suppress the “VAC cannot view your game session” error notification in CS: GO.
Why is he saying VAC Was Unable to Verify Your Game Session?
VAC (Valve Anti-Cheat System) detects anomalies in installation files. It is designed to prevent players from modifying the game files in order to gain an unfair advantage over other players.
If VAC doesn’t check your game session, but you haven’t changed your game files in any way, there is an error in the file configuration. Sometimes the VAC can also generate a false positive and display the message “The game session could not be verified.”
Check integrity of game files
- Close Steam (right-click the Steam icon in the system tray and select Exit).
- Right-click on the Steam icon (desktop or start menu) and select “Run as administrator”.
- Go to the library on Steam. Right click on Counter-Strike: Global Offensive and select Properties.
- Select the Local Files tab and click Verify Integrity of Game Files. Some files may need to be re-downloaded after the process is complete.
- Restart your computer.

Reinstall CS: GO from scratch
If the above two fixes don’t work, changing the setting or restarting your computer probably won’t fix your problem. Although we recommend that you search the internet to see if something else is right for you. However, reinstalling CS: GO will likely save you time. Reinstalling the game will quickly fix the problem, and you won’t have to try many different fixes (which probably won’t work).
- To completely reinstall CS: GO, go to your library on Steam, right-click on “Counter-Strike: Global Offensive” and select “Uninstall”:
