Hi there, I recently got a retired sever computer, and installed Debian 10 as the main OS for my physical sever. I wanted to make it into a personal VPN server, in which i installed openvpn and was setting it up from there. I created a personal VPN following this guide here
https://averagelinuxuser.com/linux-vpn-server/ after doing that i put in the command sudo openvpn /etc/openvpn/client/client.conf then i got this:

The "Unrecognized option or missing or extra parameter(s) in /etc/openvpn/client/client.conf:18: block-outside-dns (2.4.7)" I believe is the reason why i'm not really able to connect to my personal VPN on my client computer. Was there something that i may have missed or did wrong? Please be mindful this is my very first time creating a personal VPN through openvpn as a personal project. I appreciate whatever help you all can give me thanks!
