Error code 279 means something on your device is blocking or interfering with your connection to the game. Let’s take a look at some of the culprits:

1) Slow Internet Connection

Do you have a slow connection? A good way to tell is to see whether any objects in the game take longer than normal to load.

This type of poor connection can result in error code 279 or in error code 277.

2) Roblox Game

Sometimes only a few game servers experience a glitch. Maybe there are scripting errors or too many items in the game for it to handle.

If only a few game servers have this issue, it is worth reporting it to the creators so they can figure out how to fix it.

3) Windows Firewall

The configuration of your Windows Firewall can sometimes cause an error.

The correct connections for Roblox must be enabled via the Windows Firewall or else access to the game will be blocked and you will see the error.

5 Ways To Fix Roblox Error Code 279

Let’s take a look at some of the solutions for error code 279:

Fix #1: Configure Your Windows Firewall

The first step is to turn off your Windows Firewall temporarily, then reconnect to Roblox and see whether you are still getting the error.

If you can now play fine, the problem was likely your Windows Firewall, so you will have to manually allow Roblox.

Here is how to do that:

  1. Open the Start menu.
  2. Type in “Windows Defender Firewall“.
  3. Click on “Turn Windows Defender Firewall On/Off“, on the left hand side.
  4. Ensure “Turn Off Windows Defender Firewall” is checked under the private and public sections, then click OK.

Fix #2: Use Different Browser (Supported)

You need a supported browser to run the game, unless you are connected via the app on your system or device. Not all browsers will run Roblox.

Chrome, Firefox, Internet Explorer, Safari and Opera can all work with Roblox, although some users report issues when trying to play on Microsoft Edge because it is quite minimalistic.

Ensure your chosen browser is up to date, since out of date versions can cause bugs.

Fix #3: Disable Browser Add-ons from Third Parties

It has been known for browser add-ons to cause problems with Roblox. In fact, some ad-blocking add-ons can mean the game not even loading.

Disable any third party add-ons then restart your browser and try the game again.

Fix #4: Open Required Ports

It will be necessary to port forward the required range of ports for Roblox if they are not already open on your network.

This will let Roblox connect and should stop error code 279 from occurring. This is how to do that:

  1. Log in on your router control panel as an administrator.
  2. Go to the “Port forwarding” category and enter your system’s IP address.
  3. Enter “49152–65535” port range.
  4. Choose “UDP” as your protocol.
  5. Restart the router, and see if Roblox works now.
