I have Jellyfin installed on a remote machine, connected to my laptop and phone via Tailscale. Is it possible to cast from that machine to a gen 2 Chromecast?

From the Jellyfin instance installed on my laptop, in the same LAN, I can authenticate from the phone and cast to the Chromecast, so all the pieces work.

I have tried announcing the subnet from the laptop (--advertise-routes=192.168.1.0/24), with IP forwarding etc. The remote machine accepts the route and can ping the Chromecast (192.168.1.100). From the phone I can connect to the server and start casting. The screen shows the Jellyfin logo, but playing anything has no effect.

Has someone managed to make it work?

EDIT: As I feared, it seems it’s not possible. I can’t change the routing table of my ISP’s router, so the Chromecast can’t reach the remote server.

I’ll try to find a newer Chromecast, or maybe just get a Raspberry and install the full client there. Thanks everyone!

    But the stream will consume the cellular connection, because you’re using the phone’s wifi for the hotspot (the phone only has one wifi interface so it cannot use it both to connect to the local LAN and for hotspot).

    This is not necessarily true. It’s almost always possible to use the 2.4GHz band on one side and the 5GHz one on the other and multiple networks on one WiFi interface isn’t impossible either.

    Modern Android devices can provide hotspot of the connected WiFi without any modifications. For some anecdata: My FP4 with LineageOS 20 and a Samsung A50 (Android 11) can both do it.
