Cyberghost VPN

I was trying to use the default dietpi openvpn installer (as custom) to setup Cyberghost VPN, but seemed to fail.

Anyone had and success with installing the Cyberghost config/ovpn, crt's and key with the dietpi VPN package?

error:

root@Pi:/etc/openvpn# systemctl status dietpi-vpn.service
