Why Does Roblox Error Code 279 Occur?
Error 279 can be triggered by several different factors, including:
- Unstable or slow internet connection
- Firewall or antivirus software blocking Roblox
- Outdated Roblox client
- Temporary issues with Roblox servers
- Corrupted or overloaded browser cache
- Problems with specific games, especially those using heavy scripts or large maps
How to Fix Error Code 279 in Roblox
Follow these steps one by one to resolve the issue:
1. Check Roblox Server Status
Visit the official Roblox status page at status.roblox.com. If Roblox is undergoing maintenance or experiencing outages, you’ll need to wait until the servers are back online.
2. Clear Browser Cache
If you play Roblox in a browser, press Ctrl + F5 or clear your browser cache manually from the settings. Accumulated temporary files can interfere with server connections.
3. Restart Your Internet and Device
Turn off your Wi-Fi or mobile data, wait 10–15 seconds, then turn it back on. Restart your PC, phone, or tablet to refresh network settings.
4. Reinstall Roblox
Uninstall Roblox completely and reinstall it. PC users may find better stability by installing Roblox from the Microsoft Store instead of the web version.
5. Disable Firewall or Antivirus
Your firewall or antivirus software may block Roblox connections. Temporarily disable them and try launching the game again.
6. Switch Your Browser
Some browsers cause compatibility issues. Try using Google Chrome, Microsoft Edge, or Mozilla Firefox.
7. Reset Network Settings
Open Command Prompt as an administrator and run the following command:
netsh winsock reset
Restart your computer after running the command.
Error 279 Appears Only in Certain Roblox Games?
If Error 279 occurs in only one or two games, the issue is most likely game-specific, not global.
Possible causes include:
- Overloaded or poorly configured game servers

Solution
Try joining a different game. If other games work normally, the issue is on the developer’s side, not yours.
