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.
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.
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.
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.
