Solution #2: Delete Roblox Logs.

Roblox stores temporary data such as game history, settings, and other files that could take up considerable space on your computer. These files could also cause glitches or issues when you’re running the app, so you should regularly clean up these temporary files to avoid errors.

    • %USERPROFILE%\AppData\LocalLow\RbxLogs\
  5. Repeat step 3.

Try running Roblox again to check if this solution has fixed Roblox error 277.

Before 2018, the default UDP port range for Roblox was 1025-5000. After the 2018 update, the default range became 49152 – 65535. To change the opened ports on your router, follow the steps below:

  1. Find your router’s IP address by clicking Start > Settings > Network & Internet > View your network properties. Your router’s IP address is the one next to Default Gateway.
  2. Open your browser and type in the IP address to access your router’s settings page.
  3. Type in your username and password.
  4. Click on the Port Forwarding section. Each router’s settings page is different, so if you don’t see the Port Forwarding section, look for any of the following options or their variations:
    • Applications
    • Gaming
    • Virtual Servers
    • Firewall
    • Protected Setup
    • Advanced Settings
  5. Once you’ve opened the Port Forwarding section or its equivalent, open your preferred port range by filling out the required information:
    • Name/Description – Type in Roblox.
    • Type/Service Type – Enter UDP.
    • Inbound/Start – Type in 49152.
    • Private/End – Type in 65535.
  6. Next, enter your computer’s private IP address.

Click the Save or Apply button to save your settings, then restart your router for the changes to take effect. Disconnect your computer from your router, then reconnect to see if the Roblox error still exists.
