How to start openvpn via config?

Question

openvpn

Now I start Openvpn via: service openvpn start.
Everything works, but I have a server on which there are two configs: a server and an Openvpn client. Service restarts both the server and the Openvpn client at once. Therefore, to restart only the client or only the server, I decided to use the command: openvpn server.conf
But it does not work. After starting the console hangs and nothing happens.
At the same time, it is written in the logs that the client has connected. And openvpn server does work.
When you press ctrl + c, the console works again, the connection disappears and it is written in the logs
