How to Fix the Hamachi Tunnel Problem on Windows?
When you see a yellow triangle with a “tunneling problem” message in Hamachi, it means there’s a disruption in the direct connection between peers. This usually happens because the Hamachi Tunneling Engine service isn’t working correctly.
It might also be caused by problems with the Hamachi network adapter or interference from other VPN software. As a result, the connection defaults to a relayed mode, increasing latency and reducing performance.
Now that you know the causes, let’s discuss the solutions.
1. Disable and Re-enable the Hamachi Connection
Temporary problems with the Hamachi connection may cause tunneling issues. Turning the connection off and on can fix the network adapter and clear small errors or incorrect settings that might disrupt proper functioning.
- Press Windows + R to open the Run box, type ‘ncpa.cpl’, and click OK to access Internet Connection settings.
- Alternatively, open Control Panel, set “View by” to Category, then click Network and Internet. Open Network and Sharing Center and click Change adapter settings in the left menu.
- In the Internet Connection window, right-click the Hamachi network connection and select Disable. Wait a few minutes, then right-click again and select Enable. Check if the Hamachi Tunneling issue persists.
2. Restart the LogMeIn Hamachi Tunneling Engine Service
