Describe the issue

The Roon Remote app on my MacBook Air stopped connecting to Nucleus. The iPhone & iPad on the same WiFi connect and work fine.

I've tried the troubleshooting and reinstalled Roon app on my MacBook Air, but it still cannot "see" the Nucleus (Roon Server).

It has been working fine until I updated MacOS and restarted my laptop 2 days ago.

Describe your network setup

I have the Cable modem provided by Breezeline (USA), a Google WiFi router and the Nucleus & Synology (where music files are stored) are connected by ethernet to a NetGear switch

I can connect to the Synology from my MacBook Air and browser the music folder. I can see the Nucleus by going to http://nucleus in a browser on the MacBook Air.

Roon is also allowed to “find and communicate with devices on my local network” under the Privacy & Security setting on the MacBook Air.

I do not have the Apple Firewall turned on.

Currently running macOS Sequoia 15.2 (24C101)

Hi @davidmead,

Thanks for writing in!

If it is already enabled, toggle it off and on again. Then reboot your Mac, and see if the same issue persists.

Thank you!

Hi @benjamin

I tried switching that on/off and restarting, as well as turn off, restart, turn on. That didn’t make a difference.

@Benjamin Any other ideas, or news, about this issue?

@Benjamin Don’t know if this was a change on your end, or Apple’s, but all of a sudden Roon install found my Nucleus on the network, connected, and can now stream to any of my existing end-points!

It’s a Festivus miracle! :slight_smile:
