[SOLVED]OpenVPN to pfSense box/server behind it, error=unsupported certificate

[pfrickroll]

Help me to understand what I did wrong.
Why would certificate be unsupported?

Also, under configuration "IPv4 Tunnel Network" do I put local subnet of the client I am trying to connect from?

[jimp]

"unsupported certificate purpose" usually means the certificate chosen for your server was not generated as a server certificate, but as a user certificate. You may need to make a new server certificate.

IPv4 Tunnel network is a unique, unused network only for the VPN clients.

Your local network you want them to reach goes in IPv4 Local Network

It worked, and you were right it was a user's cert and not the server.

Thank you!
