The very first thing you should ensure is that you have a stable internet connection to make sure the issue isn’t at your end.

Clear Your Roblox Cache

Sometimes your game data can get corrupted due to a multitude of reasons. Corrupted files will cause the game to not work properly which might lead to the Error Code 279 error popping up.

Deleting the game to fix Error Code 279 is fine because it will just redownload a stable copy again when you reboot the site or the app. That is why I suggest clearing your cache for Roblox, to fix this error.

  2. Type %localappdata% and press Enter.

  4. Once found, press the Delete key to remove the folder.

Once done, Restart your PC so the changes take effect.

Allow Roblox Through Windows Firewall

Windows Firewall can sometimes flag and disable network access to sites or servers that are not in any way malicious. Similarly, it can block the connection to the Roblox Servers. 

That is why I recommend allowing Roblox through the Windows Firewall so it doesn’t accidentally block the connection and cause the error to pop up. People online also found this helpful.

Clear Your DNS Cache

Sometimes, the cached information of the DNS (Domain Name System) can become corrupted, leading to unexpected behavior or connection problems. Clearing the cache removes these corrupted entries and allows your device to start fresh with clean information.

So Clearing your Cache could help when fixing Error Code 279 in Roblox.

  1. Press your Win key, type cmd, and press Enter.
  2. Once opened, type ipconfig /flushdns, and hit Enter.

Disable Your Adblocker Extension

If you are playing on a browser, having an Adblocker can sometimes interfere with your connection to the game servers. This is because the advertisements on the site are the source of income for both the developers of the game and Roblox itself. To disable or delete the Adblock extension, simply:

  1. Click on the three vertical dots on the top right of your browser.
  2. Go to Extensions and click on Manage Extensions.
