✅ 1. Check Roblox Server Status

First, visit Roblox server status to confirm if the servers are down. If it is a global outage, the only solution is to wait until Roblox fixes the issue.

✅ 2. Restart Your Internet Connection

Restart your Wi-Fi router or modem to refresh the connection. If possible, switch from Wi-Fi to a wired Ethernet cable for more stability. For mobile players, turn Airplane Mode ON and OFF to reset your data connection.

✅ 3. Clear Roblox Cache and Temporary Files

Corrupted cache files often cause Roblox Error Code 277. Here’s how to clear them:

• Windows: Press Win + R, type %localappdata%\Roblox, and press Enter. Delete the “Cache” and “Downloads” folders.
• Mobile (iOS/Android): Go to App Settings → Storage → Clear Cache.

✅ 4. Update Roblox Client

Always make sure you are using the latest version of Roblox:

• PC: Reinstall Roblox from the official website.
• Mobile: Update Roblox through the App Store or Google Play.

✅ 5. Disable Background Apps

Close heavy apps like Discord, browsers, VPNs, or downloads that may consume bandwidth. This improves internet stability while playing Roblox.

✅ 6. Adjust Firewall and Antivirus Settings

Sometimes security software mistakenly blocks Roblox. Allow Roblox through Windows Firewall:

• Go to Control Panel → System and Security → Windows Defender Firewall → Allow an app.
• Make sure Roblox is enabled for both Private and Public networks.

If you use an antivirus, add Roblox as an exception.

✅ 7. Reset Network Settings

Windows: Open Command Prompt as Administrator and run these commands:

netsh int ip reset
netsh winsock reset
ipconfig /flushdns

Restart your PC afterward.

Mobile: Reset network settings in your system options.

✅ 8. Switch to Google DNS

Your internet provider’s DNS may be slow. Switch to Google’s DNS for faster and more stable connection:

• Go to Network Settings → Change Adapter Options.
• Right-click your connection → Properties → Internet Protocol Version 4 (TCP/IPv4).
• Select “Use the following DNS” and enter:

Preferred: 8.8.8.8
Alternate: 8.8.4.4

✅ 9. Reinstall Roblox Completely

If none of the above works:

• Uninstall Roblox fully.
• Delete leftover Roblox folders in AppData and LocalAppData.
• Reinstall Roblox fresh from the official website.

✅ 10. Device-Specific Fixes

• Mobile: Ensure at least 2GB free storage and close background apps.
• Console (Xbox): Sign out, restart console, and reinstall Roblox app.
• PC: Update Windows and your graphics drivers.
