CS2 Unable to Establish a Connection With the Game Server – How To Fix

Whenever you have connection issues with CS2, you should always check the official server status to ensure the issue isn’t on Valve’s end before going any further. You can visit Steamstat.us to check the current status of the servers.

Once you’ve opened the Steamstatus website, you can see all region statuses for each server on the right-hand side of the page. If your region shows “OK” in green text, the servers are good and the issue is likely to be something else.

Without an internet connection, your game won’t be able to connect to the CS2 servers. Make sure your internet connection is stable, and that you have an active connection. If your wi-fi signal is too weak or even completely inactive, this will cause an issue connecting to the game’s servers. 

You’ll also want to make sure that your firewall, or any anti-virus software, is not blocking your connection to the game. It can be a good idea to verify your internet connection by running a speed test, which will help you assess your network performance.

Whenever you have issues with CS2, you should always check the game’s file integrity on Steam. Occasionally game files can get corrupted leading to connectivity issues along with performance issues and other problems. To verify the integrity of your game files simply follow these steps:

1. Right-click CS2 in your Steam library
2. Navigate to the “Installed Files” tab
3. Click on the “Verify integrity of game files” button
4. Wait 2-3 minutes and your files should be verified!

Sometimes all it takes is a simple router restart to get things going again. Simply locate your router and unplug its power source for around 30 seconds. Once 30 seconds have passed, simply plug the power source back in, and you should be good to go. Verify that your network is working again by checking your device for a network signal.

Sometimes outdated or corrupted DNS records can cause connectivity issues. To resolve these, simply open your command prompt (CMD) by pressing CTRL + R and typing in CMD, then hitting enter. Doing this will open up the Windows command prompt. Next, you’ll simply want to type “ipconfig /flushdns” (Without quotation marks) and hit enter to run it. After the command has finished executing, simply restart your PC and check if your connection issues have been resolved.

You may have other programs running in the background that are conflicting with CS2’s ability to connect to the game servers, and potentially slowing down your game, causing performance issues such as decreased framerate (FPS).

Programs that may cause issues for your CS2 connectivity include: 

• VPN/Proxy’s
• Any launcher(s) that may be downloading games or other applications in the background
• Browsers
• File sharing apps

When having issues with your CS2 connection, you should always make sure your game and Steam client are both fully updated. Without a fully updated client and game, CS2 will not allow you to connect to any game servers.

While Steam generally stays up to date automatically, you can still check for updates manually by clicking “Steam” in the top left of your client and pressing the “Check for Steam Client Updates…” button.

You should also check for any missing updates your CS2 game may have. To do so, right-click the game in your library, press properties, go to the “Updates” tab, and under the “Automatic Updates” section you’ll want to make sure that you set it to “Always keep this game updated”. After that has been checked, Steam will verify if there are any missing updates and will install them automatically.

If none of the provided fixes resolved the issue for you, we recommend reaching out to Steam support.
