My Jellyfin tunnels via traefik and cloudflared. However, the normal Android app somehow can't login, but streamyfin works like a charm.
I always had issues with plex, because it relied on their own service. But jellyfin now simply works, pretty nifty
This. Be on the lookout for company grade PCs, like from Dell, Lenovo or Fujitsu, they come in small form factors, offer decent upgradability and are low/on power consumption and noise (most of the time)
I have a old optiplex 7010 with i7 and 8gig RAM. About 70€ on eBay. I upgraded it with a nvme SSD to bolt from (great tutorial here) and salvaged an old SATA HDD from an external case.
Currently runs 11+ container in proxmox without issues. Way beefier than a raspberry pi.
I also have room for 3 more hdds to put in a mergerfs system and 2 additional pcie slots für things like a faster LAN card or an additional SATA controller
One thing to mention, this is a torrent-based service and is probably not using legal sources. So, depending on your legal jurisdiction, be careful. For example, i would not recommend using it in Germany.
