⚠️ “Failed to connect to the Game. (ID=17: Connection attempt failed.) (Error Code: 279)”

This error means that something is blocking, delaying, or interfering with the connection between your device and the Roblox servers.

✅ Common Causes of Roblox Error Code 279

• 🐢 Slow or unstable internet connection such as weak Wi-Fi or mobile data.
• 🛡️ Firewall or antivirus software blocking Roblox network traffic.
• 📥 Outdated Roblox app or old browser version failing to sync with servers.
• 🌐 Browser issues like corrupted cache, ad-blockers, or unsupported browsers.
• 🎮 Large game maps that timeout due to low internet speed.
• 🔒 VPN or proxy settings interfering with Roblox connections.
• 📡 Router or ISP restrictions that block Roblox network ports.

🛠️ Step-by-Step Fixes for Roblox Error Code 279

1. Check Your Internet Connection

Restart your modem or router, switch to a stable Wi-Fi or wired Ethernet connection, and avoid mobile hotspots when possible. Test your internet speed—at least 5 Mbps download and upload is recommended for Roblox.

2. Use a Supported Browser (for PC Players)

Roblox works best on Google Chrome, Microsoft Edge, or Firefox. Always update your browser to the latest version, clear cache and cookies, and disable unnecessary extensions or ad-blockers that may block Roblox scripts.

3. Update or Reinstall Roblox

Update Roblox from the Microsoft Store (Windows), Roblox website, or App Store/Google Play (mobile). If issues persist, uninstall and reinstall Roblox to refresh the installation.

4. Disable VPNs or Proxies

Turn off any VPN applications and remove proxy settings. Roblox often blocks unusual IP addresses from VPNs, which can cause Error 279.

5. Check Firewall and Antivirus Settings

Ensure that Roblox is allowed through Windows Firewall and your antivirus software. Add Roblox to the whitelist or allowed apps list to prevent blocked connections.

6. Open Required Roblox Ports (Advanced Users)

Roblox requires UDP ports 49152 – 65535. Access your router settings, go to Port Forwarding, and add this port range for Roblox.

7. Try Roblox App Instead of Browser (or Vice Versa)

If you encounter Roblox Error 279 in the browser, download the Roblox app. If the app has issues, switch to playing Roblox through a supported browser.

8. Disable Background Apps

Close heavy downloads, torrents, or streaming apps that consume bandwidth. Other applications like Discord or video streaming can slow Roblox connections.

9. Check Game-Specific Issues

Some Roblox games with huge maps or heavy assets take longer to load. If the error only happens in one game, it may be a server issue with that game, not your device.

10. Device-Specific Fixes

• 📱 Mobile (iOS/Android): Clear Roblox app cache, ensure proper permissions, and update the app.
• 💻 PC (Windows/macOS): Run Roblox as Administrator, update Windows, and make sure your graphics drivers are up to date.

🚀 Quick Checklist to Fix Roblox Error 279

• ✅ Restart your router and device.
• ✅ Update Roblox and your browser.
• ✅ Clear cache and disable browser extensions.
• ✅ Turn off VPNs or proxies.
• ✅ Check firewall and antivirus settings.

📝 Final Notes

Roblox Error Code 279 is usually caused by internet connection problems or firewall restrictions. By checking your internet, updating Roblox, and making sure the app has full access to your network, you can fix this error quickly. If all fixes fail, the issue might be on Roblox’s side—check the official Roblox Status Page to confirm server outages.
