How to Fix Error Code 279 in Roblox

  • Check the status of Roblox servers: go to the official status website status.roblox.com. If technical work is indicated there, just wait for the work to be completed.
  • Clear your browser cache: if you play Roblox through a browser, press Ctrl + F5 or manually clear the cache in the settings. Often, a large amount of temporary files causes connection errors.
  • Restart your internet and device: turn off Wi-Fi, wait 10-15 seconds, and turn it back on. Also, restart your PC or phone.
  • Reinstall Roblox: if you are using the version from the website, try installing Roblox from the Microsoft Store.

  • Change your browser: the error may depend on the browser you are using. It is recommended to run Roblox through Chrome, Edge, or Firefox.
  • Reset your network settings: Open the command prompt (cmd) as an administrator and enter: netsh winsock reset. Then restart your computer.

What to do if Error 279 only appears in certain Roblox games?

This means that the error is not global, but local — related to a specific game:

  • Prohibited scripts are being used;
  • The map is not optimized (too many objects);
  • Try another game — if everything works, the problem is not on your end.

Why does Error 279 appear on mobile?

  • Restart your phone

If you've tried everything and error 279 in Roblox still persists, the problem is most likely on the game's side. Sometimes servers are overloaded or undergoing maintenance, and the fix is only available over time.
