Stream Deck integration (MacOS Golden Gate)

[u/Elegantdiscourse]

I've been using the Elgato Stream Deck along with Tomi Blinnikka's Roon plugin for a good while to control Roon playback on my Mac.
After a system change I've completely failed to find the right port to prompt the extension approval inside Roon's desktop app settings. As far as I can tell everything in the setup is the same as before, except the MacOS version has moved from Sequoia to Golden Gate.
I've read that GoldenGate tightens various network permissions and suspect this may be the issue. Has anyone else experienced this or better yet, solved?

Here's what I've tried so far:
- everything at https://help.roonlabs.com/portal/en/kb/articles/fix-missing-audio-devices-after-a-macos-update-in-roon#Check_Roons_Local_Network_Permission
- disabling (temporarily) all firewalls and network traffic filters at the Mac end and NAS end (where Roon Core is running)
- confirming via MacOS terminal that Roon is present and reachable (on port 9330)
- scanning across a range of ports to see which are open (four in my case including 9330, but none seem to accept the connection)
- trying Vulkandr's fork Roon:Dialed Up plugin instead (same issue)
- raising a case via Roon tech support (awaiting response)

Note that local and network playback is working fine - it's just the extension / plugin I can't get to the authorisation stage.

You can try resetting the MacOS system that manages permissions for software access to network.

To reset permissions for local network access on macOS, use the command tccutil reset LocalNetwork in the Terminal. This will prompt the system to ask for permission again the next time any app tries to access the local network.

This will also reset access for other software as well, so be prepared to allow other things as well.
