Unable to get Plex to see Tunarr

[photo-copy]

The subject is probably a little basic, but let me expand.

I have Plex (official) and Tunarr running in Docker containers on Unraid 6.12.11. I have both on the same VLAN (macvlan) with my other streaming devices.

Plex has no problem seeing a real HDHR on the same VLAN. As an aside, I don't use the HDHR anymore, I had it laying around to test with. As part of troubleshooting, I put both Plex and Tunarr on the same docker network. I also see SSDP traffic from Tunarr & Plex in Wireshark.

Additionally, I do have Plex added in Settings -> Sources, but it is not a healthy connection.

I'm kind of at a loss here. I do realize that this most likely is not a Tunarr issue, but I'm not sure I understand SSDP well enough to troubleshoot any further.

I hadn't had a lot of time to dig into this, but I finally had some time yesterday, and figured it out. It was because I was using ip, and not ip:port. Apparently UPnP isn't so PnP...
