How to Fix Error Code 279 on Roblox in Windows 11

Error code 279 on Roblox is a common issue that prevents players from joining games. It usually indicates a problem with your internet connection, Roblox servers, or the game’s server. This guide provides detailed steps on how to fix error code 279 on Roblox in Windows 11.

Understanding Error Code 279

Before diving into the solutions, it’s important to understand what causes this error. Error 279 typically arises due to:

  • Internet Connection Problems: Unstable or slow internet can disrupt the connection to Roblox servers.
  • Firewall Interference: Windows Firewall or third-party firewalls might be blocking Roblox.
  • Server Issues: Roblox servers themselves might be experiencing downtime or issues.
  • Router Problems: Problems with your router can prevent a stable connection.
  • Outdated Roblox Version: An outdated version of Roblox can cause compatibility issues.

Troubleshooting Steps to Fix Error Code 279

Here are several methods you can try to resolve error code 279 in Roblox on Windows 11.

1. Check Your Internet Connection

  • Restart Your Router: The simplest fix is often the most effective. Unplug your router, wait 30 seconds, and plug it back in.
  • Test Your Internet Speed: Use an online speed test to ensure you have a stable and sufficient internet connection. Aim for at least 5 Mbps download and 1 Mbps upload speed.
  • Try a Wired Connection: If you’re using Wi-Fi, switch to a wired Ethernet connection for a more stable connection.
  • Check for Other Devices Using Bandwidth: Close any bandwidth-heavy applications or disconnect devices that are using a lot of internet.

2. Check Roblox Server Status

  • Visit the Roblox Status Page: Go to the official Roblox status page (status.roblox.com) to check if there are any known server outages or issues.
  • Check Social Media: Sometimes, Roblox will announce server problems on their social media channels.

If the servers are down, there’s nothing you can do but wait for Roblox to resolve the issue.

3. Disable Windows Firewall (Temporarily)

Note: Disabling your firewall can expose your computer to security risks. Only do this temporarily for troubleshooting purposes and re-enable it immediately afterward.

  • Open Windows Security: Search for “Windows Security” in the Start menu.
  • Click on “Firewall & network protection”.
  • Select your active network (Domain network, Private network, or Public network).
  • Toggle the Microsoft Defender Firewall setting to “Off”.

Try launching Roblox again. If the error is gone, your firewall is the problem. You’ll need to configure it to allow Roblox through (see next section).

4. Allow Roblox Through Windows Firewall

  • Open Windows Security: Search for “Windows Security” in the Start menu.
  • Click on “Firewall & network protection”.
  • Click “Allow an app through firewall”.
  • Click “Change settings”.
  • Click “Allow another app…”.
  • Browse to the Roblox executable files. These are usually located in C:\Users\YourUsername\AppData\Local\Roblox\Versions. You’ll need to add both the RobloxPlayerLauncher.exe and the RobloxPlayerBeta.exe.
  • Make sure both “Private” and “Public” are checked for each Roblox application.
  • Click “OK”.

5. Clear Roblox Cache and Temporary Files

  • Close Roblox Completely: Make sure Roblox is not running in the background.
  • Open the Run Dialog Box: Press Win + R.
  • Type %temp%\Roblox and press Enter.
  • Delete all files and folders in this folder.

6. Reset Internet Explorer Settings (Even if you don’t use IE)

Roblox uses some Internet Explorer settings, even if you use a different browser.

  • Open Internet Explorer.
  • Click on the Gear icon (Tools) in the top right corner and select “Internet options”.
  • Go to the “Advanced” tab.
  • Click “Reset…”.
  • Check the box that says “Delete personal settings” and click “Reset”.
  • Restart your computer.

7. Reinstall Roblox

  • Uninstall Roblox: Go to “Apps & features” in Windows Settings, find Roblox, and uninstall it.
  • Restart Your Computer.
  • Download Roblox: Go to the Roblox website and download the latest version.
  • Install Roblox: Run the installer and follow the on-screen instructions.

8. Check for Conflicting Programs

Some programs can interfere with Roblox’s connection. Common culprits include VPNs, proxies, and certain antivirus software. Try temporarily disabling these programs to see if that resolves the issue.

Conclusion

Error code 279 on Roblox can be frustrating, but by systematically working through these troubleshooting steps, you should be able to identify and resolve the problem. Remember to start with the simplest solutions first, such as checking your internet connection and restarting your router, before moving on to more complex steps like firewall configuration and reinstalling Roblox.
