BUT when I try to create .ovpn file for windows/mac/android, and add contenct of these files to .ovpn, i cannot connect to vpn, having "Pam_pass_fail: privat key pass cannot be empty" message. I dont have any passowrd set on server. and this is working on fedora. what did I miss in .ovpn??? client dev tun proto udp remote My-Server-1 1194 key-direction 1 <ca> -----BEGIN CERTIFICATE----- -----END CERTIFICATE----- </ca> <cert> -----END CERTIFICATE----- </cert> <key> -----BEGIN ENCRYPTED PRIVATE KEY----- -----END ENCRYPTED PRIVATE KEY----- </key> <tls-auth> -----BEGIN OpenVPN Static key V1----- HERE IS ta.key content -----END OpenVPN Static key V1----- </tls-auth> THANKS
