I believe there's some general confusion.
In order to get a private VPN working you need a VPN server (or access server, as called by OpenVPN). This access server is built inside your router and you configured this correctly already.
Devices that want to connect to your private VPN require a VPN client configured for your VPN access server (your router). When you connect with this client, it usually tells you whether it's connected or not. You don't need to test any router web interface or whatever, because anything that's inside the router is or can be reachable from the outside world (i.e. internet) without VPN too, and also without port forwarding but this heavily depends on the router's configuration.
When a device is connected to your private VPN (the OpenVPN client has a nice switch that turns from orange to green when this is the case), this device is then part of your private network. In order to access Jellyfin (or any other services inside your private network) you need to connect to its private IP address, which is the address it has inside your network, for example something like 192.168.0.55:8096 or similar (check https://en.wikipedia.org/wiki/Reserved_IP_addresses).
Certificates are on a completely different page and got nothing to do with VPN, dynamic DNS, or Jellyfin itself.
