    Put the instance behind another authentication point like a VPN or reverse proxy with SSO. That will prevent the wider Internet from accessing it without legitimate users being cut off. You should be doing this with any server you operate (like Plex), but definitely one that may have legal implications.

      aaaand now you smart tv can’t connect. none of them. the clients dont even support http basic auth creds put into the URL for some crazy reason.

      for advanced HTTP-level authentication you would need to run a reverse proxy on the TV’s network that would add the authentication info. for the VPN idea you would need to tunnel the TV’s network’s internet connection at the router. or set up a gateway address in the TVs network settings that would do that. or use a reverse proxy here too so that it repeats the request to the real server.

      but honestly, this is the real and only secure way anyway. I wouldn’t be comfortable to expose jellyfin even if the devs are real experts. I mean vulns get discovered, in dotnet, jellyfin dependencies, linux filesystem, and reverse proxy, and honestly who has time to always tightly keep up to date with all that.

      that’s not to discount the seriousness of the issue though, it’s a real shame that jellyfin is so much against security

        Your smart TV is (presumably) on your local network, so you should be routing the requests locally (point the client at the local ip, assuming it didn’t autodiscover it) not through the VPN/ tunnel.

          often, but not always. sometimes the TV is at a different house, when you are a guest or at a second property

      I am sorry, I don’t think I follow, I am CGNATED anyway, so I need to use VPNs to access my server (if IPv6 is not available, for IPv4 I am experimenting with Tailscale funnels as of now).
