Thanks for your response.
I'd like to use my wildcard certificate, yes. So for that, I started with Signed Self SSL conf. I changed the frontend certificate,the private key with mine and switched "use_self_signed_ssl" off.
My server started but i had a error message : "connection error: desc = "transport: authentication handshake failed: x509: certificate is valid for XXXXXXX, not VelociraptorServer" "
So I changed the pinner_server_name. And the message error changed: "connection error: desc = "transport: authentication handshake failed: x509: certificate signed by unknown authority" "
Then I searched and found that gw_certificate and frontend certificate could be the same, so I wondered if my problem didn't come from there because the gw_certificate was auto-generated with self signed ssl conf.
So I changed and the error from my last message came.
Therefore, now with your help, I regenerated a self signed ssl conf and i added tls_certificate_filename (.pem) ,tls_private_key_filename (.key), dns_name, changed frontend certificate/private key, switched "use_self_signed_ssl" off and changed pinner_server_name.
But I've still the error message on the GUI " connection error: desc = "transport: authentication handshake failed: x509: certificate signed by unknown authority" " and it's weird because with chrome i've the cadlock which says "validated certificate" and when I click on "details", I see everything is ok with my CN, etc..
I don't put the CN of my frontend certificate in Client.Pinner_server_name, could it come from there ? But if yes i've the same problem from the last message, i can't put "*" in the server.config file.
Thank you for taking your time to help me !
