Some users of Counter-Strike: Global Offensive are reporting that they are encountering an error when trying to queue for a match. The error message states that VAC was unable to verify the game session. This problem can be quite frustrating and affects players’ ability to play the game. Fortunately, there are a number of solutions that can help fix this issue.

One of the most common reasons for this error is that the game files are damaged or corrupted. This can cause the VAC system to be unable to read the game configuration and file settings.

If this is the case, updating the drivers for the graphics card can help solve this issue.

VAC is Valve’s anti-cheat system, and its job is to detect any changes in the game installation files that might be used to cheat or gain an advantage over other players. This is done by looking for unauthorized software integration hooking into the game and attempting to change gameplay or file settings. This can be detected by VAC servers and can result in the “VAC was unable to verify your game session” error.

Occasionally, it may be necessary to restart the game to refresh the connection to the server and resolve this error. This will reset the game’s local files and reconnect to Steam. This solution should work for most users, and it is relatively easy to do.

2. Restart the game

Sometimes the vac unable to verify game session error could be solved by simply restarting the computer. This will refresh the connections to all the servers and services, allowing you to log in and play again.

Another possibility for this error is that the game files are corrupted or outdated, and this can lead to a variety of problems. You can try to fix this problem by using a repair tool, such as Steam File Repair or CleanMyPC, to restore the integrity of the game files.

In some cases, the “VAC was unable to verify your game session” error can occur due to ongoing maintenance or connectivity issues on the Steam servers. In these cases, it is a good idea to wait and try again later, or check the Steam community forums for updates on the server status.
