How to Fix Roblox Error Code 279?

The Roblox Error Code 279 stops gameplay by blocking connections to game servers. This error means there is a connection problem between your device and Roblox servers, often due to network issues or firewall settings. Common causes include unstable internet, restrictive firewall or antivirus settings, and incompatible browsers.

Other factors like ad blockers, VPNs, or high ping times can also cause this issue.

Now that you know the causes of the error, let’s discuss into the solutions.

1. Turn Off Windows Firewall

Windows Firewall may block Roblox connections, causing Error Code 279. Temporarily disabling the firewall allows Roblox to connect, resolving the issue. Re-enable the firewall after testing to keep your system secure.

1. Open the Start Menu and search for Windows Defender Firewall.
2. Select ‘Turn Windows Defender Firewall on or off’ from the left menu.
3. Select ‘Turn off Windows Defender Firewall’ for both Public and Private networks.
4. Click OK.
5. Verify if the issue still exists.

2. Make Sure You Are Using a Supported Browser

If you’re using an unsupported browser, Roblox might have trouble connecting to its servers. Switching to a compatible browser like Chrome or Firefox ensures Roblox works properly. Unsupported browsers can block key scripts or cause connection issues, so using a recommended browser usually fixes the problem quickly.

Also, make sure your web browser is up to date. If you are using Firefox or Chrome to access Roblox, ensure they are updated. Outdated browsers can cause issues, and this is one of them.

3. Disable Third-Party Browser Add-ons

Browser add-ons can sometimes cause issues. If you have installed any ad-blocker add-ons, they might prevent the game from loading. Therefore, disable these add-ons before accessing the website and check if the issue persists.

1. Open Google Chrome and type “chrome://extensions/”, then press Enter to access the Extensions tab.
   
2. Disable each extension by setting its toggle to off.
   

4. Open Required Ports

Opening the needed network ports lets Roblox connect easily to its servers, allowing data to flow without interruptions. This is helpful when firewall settings are strict, as it removes barriers that could block Roblox, leading to a smoother gaming experience.

1. Access your router settings as an administrator.
2. Navigate to the port forwarding section.
3. Set the port range to 49152–65535 with UDP as the protocol for your device’s IP address.
4. Restart your router.
5. Verify if the issue is resolved.

5. Turn Off Third-Party Antivirus

Sometimes, third-party antivirus software can wrongly block Roblox from connecting to its servers. Temporarily disabling the antivirus can help Roblox connect smoothly. This step helps check if the antivirus is causing the network access issue.
