I've never tried NordVPN Meshnet, but just want to add an alternative I've fallen in love with: Tailscale. It's amazingly simple to set up and use. Today all my devices are connected to each other, and my jellyfin service is reachable through my chromecast, phone, computer and Ipad. As well as my filehost VPS.

I've been self-hosting for quite awhile now, and these days it's such a breeze.
