I already host multiple services via caddy as my reverse proxy. Jellyfin, I am worried about authentication. How do you secure it?

My setup is: Proxmox - restricted LXC running docker which runs jellyfin, tailscale funnel as reverse proxy and certificate provider. So so don't care about jellyfin security, it can get hacked / broken , its an end road. If so i will delete the LXC and bring it up again using backups. Also i dont think someone will risk or use time to hack a jellyfin server. My strategy is, with webservices that don't have critical personal data, i have them isolated in instances. I don't rely on security on anything besides the firewall. And i try not to have services with personal sensitive data, and if i do, on my local lan with the needed protections. If i need access to it outside my local lan, vpn.

So i’ve been trying to set this up this exact thing for the past few weeks - tried all manner of different Nginx/Tailscale/VPS/Traefik/Wireguard/Authelia combos, but to no avail

I was lost in the maze

However, I realised that it was literally as simple as setting up a CloudFlare Tunnel on my particular local network I wanted exposed (in my case, the Docker network that runs the JellyFin container) and then linking that domain/ip:port within CloudFlare’s Zero Trust dashboard

Cloudflare then proxies all requests to your public domain/route to your locally hosted service, all without exposing your private IP, all without exposing any ports on your router, and everything is encrypted with HTTPS by default

And you can even set up what looks like pretty robust authentication (2FA, limited to only certain emails, etc) for your tunnel

Not sure what your use case is, but as mine is shared with only me and my partner, this worked like a charm

I'm pretty sure that using Jellyfin over Cloudflare tunnels is against their TOS, just FYI. I'm trying to figure out an alternative myself right now because of that.

Pay attention to your email, when cloudflare decides to warn you for this (they will, it's very very much against TOS) they'll send you an email, if you don't remove the tunnel ASAP, your entire account will be terminated.

Why would Cloudflare warn me against a service they themselves offer? The email authentication is all managed by them

Kinda hard because they have an ongoing bug where if you put it behind a reverse proxy with basic auth (typical easy button to secure X web software on Internet), it breaks jellyfin.

Best thing is to not. Put it on your local net and connect in with a vpn

I'm not experiencing that bug. My reverse proxy is only accessed locally at the moment though. I did have to play with headers a bit in nginx to get it working.

~~Jellyfin is secure by default, as long as you have https. Just chose a secure password~~
