RE: Can't see other clients in the "cast to" devices list - auxym - 2025-03-26

I just tried the following values for the "Published Server URIs" field:

Code:
(blank)
all=http://jellyfin.home
all=192.168.0.85:8096

No change. Should I try anything else for this setting? It's not super clear for me what it does.

Are all the clients on the same subnet/VLAN? Is your router blocking broadcasts? Are you logged in as the same user on all devices?

Yes, all on 192.168.0.0/8 subnet. I don't have any sort of special vlan stuff.

I don't think so. It's some Hitron ISP router/modem. I checked the firewall settings, this is what it says:

Code:
Minimum Security (Low):

No application or traffic is blocked.

Allow (LAN-To-WAN):All

Blocked:
IDS enabled
IDENT (port 113)

If there's some test I can do (nmap?) to confirm, please let me know.

Yes, both JMP clients are logged in with the same client.

Are all the client devices connected via WiFi? Is "AP Isolation" enabled?

I've been fighting with these same issues since day one with Jellyfin.

I can get clients to see each other for limited periods, but only after restarting them.

The best information I've been able to find suggests that it's "Webhook" related - whatever that means.


Running Jellyfin as a container, ports 7359 and 8096 are forwarded, I had 2 additional ports configured that brought the most success, but in following this thread I just changed from Bridge to Host mode and lost all the ports - so I don't recall what they were.

The 2 main clients are Windows based (Firewall disabled), another is Android, another is Linux. They all exhibit the same problem.

From what I could find on google, and digging around on the router's settings, there is no such option on this particular router.

Also, I don't have other issues communicating between different PCs on wifi. For example, I can ssh into the other machine from my laptop, or mount a samba share, etc.

I am out of ideas.  AFAIK, it should just work for hosts on the same subnet. And even for remote devices if you're logged into both. I don't recall if this requires web sockets or not. But that would only be something to consider if you're using a mis-configured reverse proxy.

In my case, they're all on the same subnet, doesn't matter if they're wired or wireless. And sorry, yes, not Web hooks - web sockets. I have no idea what a reverse proxy is, so I can't off any input there.

Here's the Github page I came across that seems to be best related to the problem -

Well damn, that was it. I enabled websocket support in nginx-proxy-manager and it works now!

Thanks for posting that. And thanks @TheDreadPirate for all the help too, much appreciated!

Lucky you, I don't have that option since I don't use NGINX!

This thread has helped me come up with a workaround at least, I shifted Jellyfin to run in Host mode, and now all my DLNA devices are showing up under Cast, so that's a first, and a good sign.

Update: Remote control still isn't working properly. No indication of what's playing, very limited transport controls.
