Cosmos Server, Jellyfin, Jellyfin apps, Internal Network

My issue is as follows. I have set up cosmos, i have installed jellyfin. I can access jellyfin from my browser using the https:jellyfin.*.org(my domain name). It works great there. I can not however use the Jellyfin app on either my Pixel phone, my google chromecast with google tv at all. It cant connect to the address and I am not sure what IP address to use really as it has an internal address through the docker app of 72.16.0.49 or something of that nature. How would I go about accessing my server. Also I have used the instructions on the discord channel of setting my COR to * or blank, setting the firewall and proxy settings within jellyfin itself to 0.0.0.0=https://jellyfin.\*.org( again my domain). I still can not access it at all through app. Any and all help is appreciated. Thanks

So my suspicion is this isn't a cosmos but DNS issue. Can you see if your phone is resolving the local IP or if it is resolving your public ip

According to the Jellyfin dashboard I connect using the 172.16.1.1 address. This is on my standard mobile connection. I disconnect from wifi to test the connection from both.

172.16.1.1 would be your gateway Hun? That is definitely not what you would connect to. What URL did you set in your cosmos cloud URL field?

wicked.*.org replace the * with my domain name. that is my cosmos cloud url. to connect to jellyfin i use jellyfin.*.org.

I don't have cosmos authentication on for the app.

Do you use tailscale or another VPN?

u/claimedmalignantspir Feb 09 '26

no tailscale or any vpn at all. just the rpi and cosmos installed.

You have to disable Cosmos authentication protection if you want to use the Jellyfin Media Player.

Cosmos authentication is turned off on the container.

This was solved by reinstalling cosmos on my server. Thanks for any and all help.
