The first and most crucial step when encountering the “VAC was unable to verify your game session” error in CS2 is to make sure you haven’t been VAC-banned. Attempting to resolve the error without confirming your VAC status can be pointless, as a VAC ban will prevent you from playing CS2 online.

Here’s how to check your VAC status:

  • Click on ‘Steam’ located in the top left corner of your screen.
  • Then, click on ‘Settings.’
  • Under the ‘Account’ tab, you’ll find your ‘VAC status.’

If your VAC status shows that you’ve been banned, it means you’ve violated the rules, and you won’t be able to play CS2 online with that account.

Sync Your PC Date & Time

Sometimes, your PC time can reset due to either a CMOS reset or simply due to your PC failing to establish a connection with the Windows Time Update server. If your PC time isn’t proper according to your geo-location, it won’t match up with the CS2 servers you’re trying to connect, resulting in an error. 

To resolve this, I suggest you open up the Date and Time settings on your PC, set the appropriate timezone, and enable the “Set Time Automatically” option.

This will keep your time and date updated so you don’t face this issue in the future. Other players in the community are also reporting that syncing their date and time solved this issue


Verifying Files After an Update

If you’re getting the “VAC was unable to verify your game session” error in CS2, especially after a game update, it’s often because some game files got messed up or are missing. To solve this problem, you need to verify your game files. Here’s our guide on it if you need any help.

This action checks if any of the game’s important files are damaged or gone. If it discovers any issues, it will automatically download and replace those files, which should usually fix the error.

Change Steam Profile Name And Avatar

It may sound odd, but you can also fix this CS2 error by simply changing up your Steam profile name and picture. Any official recommendations don’t support this fix, but it has worked for some players.

Here are the steps to give it a try:

  1. Begin by launching Steam and clicking on your ‘Profile’ name, which is usually located next to ‘Community.’
  2. Next, look for and click on the ‘Edit Profile’ button, often found below the number of years you’ve been using Steam.
  3. In the ‘General’ tab, you can change your profile name to something different.
  4. To change your profile picture, go to the ‘Avatar’ tab and select a new image.

It’s essential to note that there’s no clear technical explanation for why this method works, but it’s worth trying if you’re struggling with the “VAC was unable to verify your game session” error in CS2. Sometimes, seemingly unrelated changes can refresh your account’s connection and potentially resolve the issue. 

Start a Practice Mode and Leave

In addition to the steps I’ve discussed earlier, such as verifying your game files and checking your VAC status, another workaround that has worked for many CS2 players is starting a practice game with bots and then leaving.

Here’s how it works:

  1. Launch CS2 and enter the main menu.
  2. Choose “Play,” then Practice,” and select any map.
  3. Begin the game by clicking “Go.”
  4. You can play for a short time. A minute or two should be sufficient.
  5. Now, attempt to play CS2 in the regular online mode. 

I’m fairly confident that you’ll resolve your CS2 issue by attempting this method.
