OpenVPN connection works when started manually, but not via systemd

Hello,

I've been working on getting my OpenVPN connection set up. The strange thing is, it works great when I start it manually via

openvpn /etc/openvpn/vpnunlimited.conf

...but when I try to start it with

systemctl start openvpn@vpnunlimited.service

it always fails.

Here's the result of journalctl -xe

Re: OpenVPN connection works when started manually, but not via systemd

/usr/bin/expect is not used on my machine when running OpenVPN via systemd. What does `systemctl cat openvpn@` print?
