Hi Scott_The_ethan! So the Error Code 277 in Roblox typically indicates disconnection from the game server, and you're right to notice that Windows 11 may be playing a role in your case. There's so much explanation for that but i will just provide you some troubleshoot you might consider to resolve your problem Step by step
1.Update Network Drivers
Press Win + X → Device Manager → Network Adapters → Right-click your adapter → "Update Driver"
- Run Roblox as Administrator
Right-click Roblox icon → “Run as Administrator”
- Adjust Compatibility Settings
Right-click Roblox Player → Properties → Compatibility tab → Check "Run this program in compatibility mode for Windows 10"
- Disable Power Saving for Wi-Fi
Control Panel → Network and Sharing → Adapter settings → Right-click Wi-Fi → Properties → Configure → Power Management tab → Uncheck “Allow the computer to turn off this device to save power”
- Allow Roblox Through Firewall
Settings → Privacy & Security → Windows Security → Firewall & network protection → Allow an app → Add Roblox if it’s not there
- Try DNS Change
Sometimes a DNS issue can cause this. Try switching to:
Primary DNS: 8.8.8.8
Secondary DNS: 8.8.4.4 (Google DNS)
