I'm trying to install openVPN on ubuntu from this tutorial - How To Set Up an OpenVPN Server on Ubuntu 16.04

in Step 9: Start and Enable the OpenVPN Service

when I enter:
sudo systemctl status openvpn@server

I get the following output and then Terminal freezes and I can't do anything other than close Terminal and kill the process:
