Whether you are using Hamachi for gaming, remote work, or file sharing, these tips will help you stay connected without hassle.

Quick Note Before You Begin

  • Make sure your internet connection is stable and working properly, as Hamachi requires internet access to function.
  • Check that you have the latest version of Hamachi installed. Older versions may have compatibility issues with Windows 10.
  • Ensure that your Windows 10 system is up to date with the latest updates and security patches.
  • Close other VPN or firewall applications temporarily, as they can sometimes conflict with Hamachi.

Step 1: Restart Hamachi and Your Computer

Sometimes, the simplest solution is the most effective. Restarting Hamachi can clear minor glitches or stuck processes. Follow these steps:

  1. Right-click the Hamachi icon in the system tray (bottom-right corner of your screen).
  2. Select Exit or Quit to close the program completely.
  3. Wait a few seconds, then reopen Hamachi from the Start menu or desktop shortcut.
  4. If the problem persists, restart your computer to refresh all system processes.

Why this helps: Restarting clears temporary issues and resets network services related to Hamachi.

Step 2: Check Hamachi Service Status

Hamachi relies on a background service to operate. If this service is not running, Hamachi won’t work correctly.

  1. Press Windows + R to open the Run dialog box.
  2. Type services.msc and press Enter.
  3. In the Services window, scroll down and find LogMeIn Hamachi Tunneling Engine.
  4. Check the Status column. If it’s not running, right-click it and select Start.
  5. Also, make sure the Startup Type is set to Automatic. To change it, right-click the service, select Properties, and choose Automatic from the drop-down menu.

Why this helps: The Hamachi service manages your VPN connections. If it’s stopped, Hamachi cannot function.

Step 3: Disable Windows Firewall or Add Hamachi to Allowed Apps

Windows Firewall or third-party firewalls may block Hamachi, preventing it from connecting properly. You can either temporarily disable the firewall or create an exception for Hamachi.

To Add Hamachi to Firewall Exceptions:

  1. Open Control Panel and go to System and Security > Windows Defender Firewall.
  2. Click Allow an app or feature through Windows Defender Firewall on the left panel.
  3. Click Change settings and then Allow another app…
  4. Browse to the Hamachi executable, usually located at C:Program Files (x86)LogMeIn Hamachihamachi-2-ui.exe.
  5. Add Hamachi and ensure both Private and Public checkboxes are checked.
  6. Click OK to save changes.

Alternative: Temporarily disable Windows Firewall by clicking Turn Windows Defender Firewall on or off and selecting Off for both private and public networks. Remember to re-enable the firewall after testing.

Step 4: Reset Hamachi Network Adapter

Hamachi creates a virtual network adapter on your system. Sometimes this adapter may malfunction and need a reset.

  1. Press Windows + X and select Device Manager.
  2. Expand the Network adapters section.
  3. Locate the adapter named something like LogMeIn Hamachi Virtual Ethernet Adapter.
  4. Right-click the adapter and select Disable device.
  5. Wait a few seconds, then right-click it again and choose Enable device.

If disabling and enabling doesn’t help, you can uninstall the adapter and then reinstall Hamachi to recreate it.

Step 5: Check Your Network Settings

Hamachi requires proper network settings to work well. Sometimes, incorrect DNS or IP configurations can cause problems.

  1. Open Control Panel and go to Network and Internet > Network and Sharing Center.
  2. Click Change adapter settings on the left.
  3. Right-click the Hamachi adapter and select Properties.
  4. Double-click Internet Protocol Version 4 (TCP/IPv4).
  5. Make sure Obtain an IP address automatically and Obtain DNS server address automatically are selected.
  6. Click OK to save changes.

Restart Hamachi after adjusting these settings.

Step 6: Run Hamachi as Administrator

Sometimes Hamachi needs elevated permissions to function correctly.

  1. Right-click the Hamachi shortcut or executable.
  2. Select Run as administrator.
  3. Check if Hamachi connects successfully.

To always run Hamachi as an administrator:

  1. Right-click the Hamachi shortcut and select Properties.
  2. Go to the Compatibility tab.
