openvpn-install: Can't connect to the VPN, RNG errors

Ubuntu server 18.04.2, all packages up-to-date OpenVPN 2.4.4

Client can’t connect. What I’ve noticed is while generating a new client with the script, I get a few random generation errors:

Client testclient added, the configuration file is available at /home/user/testclient.ovpn.
Download the .ovpn file and import it in your OpenVPN client.

Also I’ve noticed that the .ovpn files are a lot smaller than they used to be in older script releases. My old scripts with cipher AES-128-CBC, tls-cipher TLS-DHE-RSA-WITH-AES-128-GCM-SHA256 and tls-auth are 219 lines, while the file generated with this installation (default security settings) only gives files 76 lines long. Maybe these two things are related?
