Help with Jellyfin Reverse Proxy on HEXOS + SCALE + Tailscale

[YONI]

Hi everyone, I’m running Jellyfin and  I want a single hostname that works both locally and remotely via Tailscale without manually switching servers in the Jellyfin app (beacause my famaliy is not very eager to learn when to switch) . I tried using a Tailscale MagicDNS domain but it returns DNS_PROBE_FINISHED_NXDOMAIN on Windows when Tailscale isn’t running locally. I enabled WebSocket support in the HEXOS proxy manager and set the reverse proxy to forward requests to the internal IP, but it still doesn’t work for both LAN and Tailscale clients. My goal is to have stable reverse proxying for Jellyfin that handles access via local ip internally and via 100.x.x.x Tailscale IPs externally without needing to switch URLs manually in the client.

Did anyone tried to do it and have a solution ?

(open for an alternative sence im pretty new to this is my first time setting up somthing like that 😅)

If this is not the right place to post this please let me know 
thanks!
