Luckily, this guide has compiled a list of possible causes for the Roblox279 error code and troubleshooting solutions to fix the same issue.

Reasons behind Roblox error 279

  • The game cannot be accessed if the Windows Defender Firewall blocks the game/application due to content filtering. We recommend allowing the game or temporarily disabling Windows Defender Firewall to fix the issue.
  • Similarly, you will get this error if your antivirus blocks the app. Temporarily disable it to see if the issue is fixed.

  • Suppose your network connection is slower than the basic requirements of your game or application. In that case, it will be unfit to establish a stable internet connection to the game server, causing such errors.

  • Such errors occur when a necessary game element is missing or corrupted. I get a blank screen and no sound. If this happens, you will have to reinstall the game.

  • Adding too many browser extensions to your web browser can cause this error. Also, if you’re using an older browser, you may get the same error code.

  • You need to prepare DNS tag-level port forwarding technology to avoid this problem. Updating your IP address, changing your DNS server, or setting up port forwarding on your router may fix this issue.

Regardless of the reason, you can easily fix Roblox error code 279 on Windows 10 by following the below-listed troubleshooting solutions.

Method 1: Troubleshooting Router Settings

Use any options to troubleshoot internet connection issues and fix Roblox error 279.

Option 1: Reboot your router.

Rebooting your router will restart your network connection. Few users have reported that rebooting their router puts all certain changes to configuration settings into effect.

  1. Find the button on the back of the router. Press the button twice to power off your router.
  2. Unplug the power cable and wait until the power is completely drained from the capacitor.
  3. Wait 30 minutes before power cycling and wait for it to reconnect to the network.

Option 2: Enable Port Forwarding

Roblox includes a set of port ranges required to establish a stable network connection with your router. You will get this error if you need more ports to open. You can enable this port forwarding feature by following the steps below.

Port forwarding settings depend on your router’s make and model.

  1. Search the default gateway address command in the router’s config / all command prompt, as shown below.
  • Launch your web browser and navigate to the address default gateway of your router.
  • Login credentials and username here.

  • Then enter the port UDP as follows:


UDP: 49152-65535

TCP: 3074

  1. Finally, click the “Save” “Implementation” to save your changes.
  2. Now restart your router and computer. Check if the issue is resolved.

Resetting the router returns it to its factory settings.

All settings and preferences, such as forwarded ports, blocklisted connections, credentials, etc., will be erased.

After resetting, the router will return to its default settings and authentication password.
However, to reset your router, note all these details before following these steps.

  1. Open Router Settings and log in using the default gateway IP address.

  3. Press the Reset Router button for 10-30 seconds.

You must use a pointing device such as a pin or toothpick to press the reset button.

  1. The router will power off automatically, then turn it on again. You can release the button when the light starts blinking.
  2. Re-enter the configuration details of the router on the web page and reboot the router.
