Troubleshooting Steps to Fix Error Code 279

Follow these troubleshooting steps in order to resolve the issue:

1. Check Your Internet Connection

The first and most basic step is to ensure you have a stable and active internet connection.

  • Restart Your Router and Modem: Power cycle your modem and router by unplugging them, waiting 30 seconds, and plugging them back in.
  • Run a Speed Test: Use an online speed test to verify your internet speed. If it’s significantly lower than your plan’s speed, contact your ISP.
  • Check Your Wi-Fi Signal: If using Wi-Fi, ensure you have a strong signal. Try moving closer to the router or using a wired connection.
  • Ping Test: Open Command Prompt (Windows) or Terminal (macOS) and type ping roblox.com. Check for packet loss or high latency.

2. Disable Firewall and Antivirus Temporarily

Your firewall or antivirus software might be mistakenly blocking Roblox. Temporarily disabling these programs can help determine if they are the cause of the error.

  • Disable Windows Firewall: Go to Control Panel > System and Security > Windows Defender Firewall. Choose “Turn Windows Defender Firewall on or off” and disable it for both private and public networks.
  • Disable Antivirus Software: Right-click on your antivirus icon in the system tray and choose to disable it. The exact wording will vary depending on your antivirus software.

Important: Remember to re-enable your firewall and antivirus software after testing to protect your system.

3. Clear Roblox Cache and Cookies

Corrupted cache files can sometimes cause connection issues. Clearing the Roblox cache can resolve this.

  • Locate the Roblox Cache Folder: The location of the cache folder varies depending on your operating system.
    • Windows: %localappdata%\Roblox\Versions
    • macOS: ~/Library/Caches/Roblox
  • Delete the Contents: Delete all the folders and files within the “Versions” folder (Windows) or the “Roblox” folder (macOS).

4. Reinstall Roblox

A fresh installation of Roblox can fix issues caused by corrupted game files.

  • Uninstall Roblox: Go to Control Panel > Programs and Features (Windows) or Applications (macOS) and uninstall Roblox.
  • Delete Roblox Folders: After uninstalling, manually delete any remaining Roblox folders from the following locations:
    • Windows: %localappdata%\Roblox and %temp%\Roblox
    • macOS: ~/Library/Caches/Roblox and ~/Library/Application Support/Roblox
  • Reinstall Roblox: Download the latest version of Roblox from the official website and install it.

5. Check Roblox Server Status

Sometimes, the issue isn’t on your end but with the Roblox servers themselves. Check the official Roblox status page or community forums for any reported outages or maintenance.

  • Roblox Status Page: Check the official Roblox status page to see if there are any ongoing server issues. Look for announcements regarding downtime or maintenance.
  • Community Forums: Check the Roblox forums or social media groups for other users reporting similar issues. This can confirm if it’s a widespread problem.

6. Update Your Network Drivers

Outdated network drivers can cause connection problems. Updating them can improve network stability.

  • Windows: Go to Device Manager > Network adapters. Right-click on your network adapter and choose “Update driver”.
  • macOS: macOS usually handles driver updates automatically. Check for system updates in System Preferences.

7. Disable VPN or Proxy Server

VPNs and proxy servers can sometimes interfere with Roblox’s connection. Disabling them can help resolve the issue.

  • Disable VPN: Disconnect from your VPN if you are using one.
  • Disable Proxy Server: Go to Internet Options > Connections > LAN settings and uncheck “Use a proxy server for your LAN”.

8. Flush DNS Cache

Flushing your DNS cache can resolve issues caused by outdated DNS information.

  • Windows: Open Command Prompt as administrator and type ipconfig /flushdns.
  • macOS: Open Terminal and type sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder.

9. Check Router Settings

Ensure your router’s firewall isn’t blocking Roblox. You may need to add Roblox to the allowed list.

  • Access Router Settings: Log in to your router’s configuration page through your web browser (usually by typing 192.168.1.1 or 192.168.0.1).
  • Check Firewall Settings: Look for firewall settings and ensure Roblox is not being blocked. Consult your router’s manual for specific instructions.
  • Port Forwarding (Advanced): In some cases, port forwarding might be necessary. Consult Roblox’s documentation or forums for specific port requirements.

10. Contact Roblox Support

If none of the above steps work, contact Roblox support for assistance. Provide them with detailed information about the error, the steps you’ve already tried, and your system configuration.
