What is error code 279 in Roblox?    

Roblox Error Code 279 is a connection-related error that occurs when your device is unable to establish a stable link with Roblox's game servers.

This error is frustrating as it disrupts gameplay, especially for frequent users or those enjoying fast-paced games. Luckily, Error Code 279 is usually minor and can be fixed with simple troubleshooting.

How to fix Roblox error code 279 

If you’re encountering Roblox Error Code 279, here are several troubleshooting steps you can take to resolve the issue:

1. Check if Roblox servers are down
2. Restart your device and router
3. Update Roblox
4. Run a speed test
5. Use a different network or wired connection
6. Check your firewall and antivirus
7. Disable VPN or proxy services
8. Reinstall Roblox

Check if Roblox servers are down

Before adjusting your device, verify if Roblox's servers are down. Sometimes, the issue lies with Roblox itself rather than your connection. Visit websites like DownDetector to see if there are server outages. If Roblox's servers are down, you'll need to wait until the issue is resolved.
 

Restart your device and router

A quick restart often solves connection problems. Reboot your device (PC, phone, tablet, or console), and restart your router to refresh your network connection. Wait a couple of minutes for your router to reconfigure, then relaunch Roblox to see if the problem persists.

Update Roblox

Make sure you’re using the latest version of Roblox. An outdated version can cause connectivity issues.

Keeping the app updated also ensures you have the latest bug fixes and improvements.

Run a speed test

Roblox requires a stable internet connection of at least 4-8 Mbps. If your speed is slower, this could cause Error Code 279. Use a service like SpeedTest to check your connection speed. If your speed is too low, try moving closer to the router, using an Ethernet cable, or switching to a faster network.
 

Use a different network or wired connection

Is your Internet speed slow? Try switching to another network or using a wired connection (for PC users). A wired Ethernet connection is more stable than Wi-Fi and can resolve connection issues. Alternatively, if you have a mobile data plan with enough data, try using a mobile hotspot to see if the problem is network-related.

Check your firewall and antivirus

Firewalls and antivirus software can block Roblox from accessing the internet. To fix this:

• For Windows: Open "Windows Defender Firewall" and allow Roblox through the firewall. Go to "Allow an app or feature through Windows Defender Firewall" and ensure Roblox is checked.
• Antivirus: Temporarily disable your antivirus or switch to "Game Mode" to prevent it from blocking Roblox.

Disable VPN or Proxy Services

Using a VPN or proxy service can sometimes interfere with Roblox’s ability to connect to its servers, especially if the VPN is slow or blocks specific ports. If you have a VPN or proxy enabled, disable it temporarily and try reconnecting to Roblox. Once disabled, your device will establish a direct connection to the Roblox servers, which might resolve Roblox error code 279.

Reinstall Roblox

As a last resort, uninstall and reinstall Roblox. A fresh install can resolve corrupted files or persistent issues that could be causing Error Code 279. Completely remove Roblox from your device, then download and reinstall the latest version from the official website or app store.
