I'm trying to connect my Jellyfin app to my server, but I'm getting an "unable to reach server" error.

I'm accessing it via a local IP address and within the local network.

When using the local IP address via a browser, it works fine, but when I input the same IP address into the app, I get the error.

However, the app can access the server via Tailscale Funnel but not the Tailscale VPN IP address of my server.

I configured my Jellyfin via CasaOS.

Any help is appreciated right now, as I can't figure out what's wrong anymore.

I'm not sure if this is the right place to ask, but where can I find cheap PCs? The specs don't need to be high-end, as I'm planning to start a home server and possibly cluster multiple PCs. Stuff like mini PCs is a bit more preferred for space reasons.

When I plug in a device via wired connection, my wireless devices can't communicate with it. I checked that both IP addresses are on the same subnet, so I'm not sure what the problem is. For context, the router is a ZTE F670. I have a landline and cable as part of my subscription. Any help is appreciated.
