Thank you for posting on the forum! It could be that you have to adjust your Firewall settings: 1.) In the Windows Start Menu Search Bar, type "Allow an app through Windows Firewall" and click on the primary result. 2.) Click on the Change Settings button and then the Allow Another App button towards the bottom. This will open another window for you to select the app you would like to add. Click the browse button. Now navigate to the VPN by going through the following path: This PC > Windows (C:) > Program Files > Mozilla > Mozilla VPN > MozillaVPN.exe. Double click on this last file (MozillaVPN.exe). You'll now be returned to the initial "Add an app" box and should should the VPN listed. 3.) Click the "Add" button. You'll be returned to the main control panel window with all of your allowed apps listed. Ensure the MozillaVPN has both the Private and Public boxes next to it check marked and click "Okay" at the bottom. 4.) Restart your system. If your issue persists it would be best to contact us directly via the Mozilla VPN app, as we might need some additional information from you.
