I’m in the exact same boat. I have a Jellyfin server configured and ready to go whenever something happens to really piss me off. This nearly was it until I saw that my lifetime Plex pass I bought 10 years ago will make it still be free for my family.

It’s probably that. While on cellular my IP isn’t 192.0.0.4 (but it is in 10. space), but there’s probably some v6 somewhere in the way.

I can’t get it to have network connection while my phone is on cellular data. On wifi it’s fine.
