The instructions provided here are lacking information about activating a Pritunl VPN profile from a file, bypassing the URI method.
In many secure environments, only the UDP port for direct client-server VPN communication is open, without access to the WebUI. In such cases, importing the profile via a file is the only reliable way to establish a connection.
You can add profile by file using:
pritunl-client add example_profile.tar
*Please note: The client does not support direct .ovpn file activation; the profile must be in the .tar format exported from the Pritunl server.
