Behind vpn and dns. No connection

[ThomasPGH]

I can connect fine with jellyfin outside my home when i have disabled the vpn. But that's not what i want. 

I believe this is one of your issues. Ther server's address in the Jellyfin client you use to connect from outside your network is not the server address you should use when your're connected via your VPN, which is 192.168.218:8096.
Your outside server setting should in theory also work but I cannot figure out what you've configured and what you haven't. I also don't know what you got from this ovpn.com and what influence this has on your config but you certainly don't need it.

Did you read the OpenVPN documentation at https://openvpn.net/community-resources/how-to/ ?
The document tells you what you need to do to connect to other machines in your home network. If your OpenVPN server is on/inside your router, your Jellyfin server is an other machine. Check out the chapter about bridged and routed mode. Post screenshots of your router/VPN config.
