Hello, I have recently encountered problems with connecting to AirVPN via the network manager in ubuntu 16.04. I followed the guide correctly and the gnome network manager plugin is installed and works correctly. I have downloaded the correct configs and separate files, and everything is configured to work correctly. When I use firefox or even ping www.google.com i get no response and firefox doesnt connect, even though i get a message that the VPN connection is established successfully. Any fix for this? Could this be related to DNS issues or something ?
