Got my Jellyfin up and running, using Tailscale, all that good stuff. Running on a linux (arch btw) desktop, downloaded it straight to it, not using Docker. I am able to get into Jellyfin via browser on desktop and on phone, but can’t get into it on anything else anywhere else. How do I resolve this? I have been trying to pour over the reading and feel like I’m missing something.
Last I checked, Roku doesn’t have a Tailscale app. So unless Tailscale is working on your router the TV can’t see the desktop’s Tailscale IP.
I have a similar setup, and Roku only works if I connect to Jellyfin with the LAN IP. If your desktop isn’t on the same LAN – wifi or ethernet – it won’t work.
