TAP driver error when connecting to a VPN

To make sure your issue is caused by the TAP driver, you can check the connectivity logs from the NordVPN app:

1. Open the NordVPN app.
2. Go to Settings -> Advanced -> Run Diagnostics Tool -> Click on Collect Diagnostics and complete the process.
   
   
   
   
3. Open the NordVPN app installation folder and find the Diagnostics folder. By default, it is located at C:\Program Files\NordVPN\
4. You will see a .zip folder with the date of the diagnostics. Example: 2020-07-14 15_24_30Z-logs.zip.
5. Double-click on the .zip folder and locate the service-XXXX-XX-XX.nwl file. Example: service-2020-07-14.nwl.
   
   
    
6. Double-click on the .nwl file, open it with your favorite text editor, and check for the errors below.

You may notice one of these error messages:

1. FATAL:All TAP-Windows adapters on this system are currently in use.
   
   Usually, restarting the TAP adapter helps in this case. To restart it, follow these steps:
   
   1. Go to Control Panel -> Network and Sharing Center -> Change Adapter Settings.
   
   
   
   2. One of the local area connections will have an under-name TAP-NordVPN Windows Adapter v9.
   
   
   
   3. Disable it and enable it again. Try to connect now.
    
2. FATAL:There are no TAP-Windows adapters on this system or FATAL: Blocking DNS failed.
   
   In this case, you should reinstall TAP drivers. You can download them here:
