TAP adapter not installed


The TAP adapter is part of OpenVPN and important to establish a VPN connection. VPN connection is not possible without a TAP adapter.

The TAP adapter is installed together with OpenVPN during the installation of aLobby.

Error message

The following error message is usually displayed in the vpn.log:

There are no TAP-Windows adapters on this system. You should be able to create a TAP-Windows adapter by going to Start -> All Programs -> TAP-Windows -> Utilities -> Add a new TAP-Windows virtual ethernet adapter.


All TAP-Windows adapters on this system are currently in use.

This solution is valid for Windows 7, Windows 8, Windows 8.1 as well as Windows 10:

  1. Open your control panel.
  2. Go to the “Network and Sharing Center”.
  3. Open the adapter settings (on the left)
  4. Activate there the TAP interface responsible for the VPN
  5. Usually called “TAP-Windows Adapter V9”.
  6. Right click > activate.
  7. Done.

After that you can establish a VPN connection to the siedler3.net server in the aLobby.

Reinstall the aLobby, making sure that OpenVPN is installed with the TAP adapter.
