One issue that has been annoying the players in CS2 is the “VAC was unable to verify game session” error. This can be quite frustrating for avid gamers, but there’s a solution that has proven effective for many.
The VAC (Valve Anti-Cheat) system is designed to detect cheats installed on users’ computers. If any modifications are identified by this system, it prevents the user from accessing the game’s online multiplayer mode. The “VAC was unable to verify game session” error, however, is not necessarily an indication of cheating. It might be a result of some internal issues with Steam or the game files.
How to Fix CS2 Vac Was Unable to Verify Game Session Error?
Here’s a step-by-step guide based on how to fix the issue:
- Switch to Offline Mode on Steam: Before making any changes, ensure that Steam is set to Offline Mode. This can be done from the main menu.
- Restart Steam as Administrator: Close the Steam application. Right-click on the Steam icon and select ‘Run as administrator’. This ensures that Steam has all the necessary permissions.
- Switch Back to Online Mode: Once Steam is running with admin rights, revert it back to Online Mode.
- Verify Game Files: Go to the game library, right-click on the game showing the error, select ‘Properties’, and then ‘Local Files’. Click on ‘Verify Integrity of Game Files’. This process might take a few minutes, but it will ensure all game files are intact and up-to-date.
