Step 1: Check the Network Configuration
The first thing to verify is your network configuration. Ensure that your local machine is on the same network as the Avocent UMG 4000 appliance.
- Verify that the UMG 4000 is properly connected to the network.
- Test the network connection by pinging the 127.0.0.1 loopback address. Open Command Prompt or Terminal and type:
If the ping test fails, there might be an issue with your network configuration or the Avocent device.
Step 2: Restart the Avocent UMG 4000
Sometimes, restarting the Avocent UMG 4000 can solve the issue. Power cycle the device by turning it off and on again.
- Wait for the system to fully reboot.
- Once rebooted, try accessing 127.0.0.1:8128 again from your browser.
Step 3: Clear Browser Cache and Cookies

- Port 8128 may be blocked by your system’s firewall, preventing the webpage from loading. To resolve this:
- Access your firewall settings (Windows Defender Firewall, or the firewall used by your OS).
- Check if port 8128 is being blocked. If it is, you need to allow traffic through that port.
