Sorry, why would Jellyfin be different from Plex for exposing to the Internet? Dynamic DNS service / static IP and router port forwarding just like any other self hosted thing. It requires a user/pass to login as usual. VPN is nice but not required.
I got my account locked on BLU because I stopped seeding when my RAID went down. I was able to recover the data and get back up in about 24 hours but there was literally no recourse other than begging some random mod’s reddit account.
Always sad to see a tracker go down, but this place was a shit show.
So it’s not fully self hosted then? I can’t see how it would do that without registering you with their own service as a middle man. Seems like that kinda defeats the purpose.
