Hello I’ve run into the same error and the solution for me was to :
systemctl enable openvpn-server@server.service
instead of “openvpn@server.servcice”
then start the service:
systemctl start openvpn-server@server.service
I assume your config file is server.conf and it’s under /ets/openvpn/server folder
hope it helps
Hi guys,
Mine was resolved on Ubuntu 16.04 when I realised that the /etc/openvpn folder was missing the DH file. I opened the server.conf and took an openssl command from a comment there:
openssl dhparam -out dh2048.pem 2048
Once I run this I could run sucesfully
systemctl start openvpn@server
-J
Doh! I forgot to copy the ta.key file to the /etc/openvpn directory. I discovered this by running the suggested command:
sudo journalctl -xe
Found this beauty: Options error: --tls-auth fails with ‘ta.key’: No such file or Options error: Please correct these errors.
Hope it helps.
