· Yes, Roon Server is turned on and running.

What do you see on your screen?

Sometimes the issues can be resolved with a reinstall of your Roon Remote app. Let's try to perform a reinstall and see if it helps.

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

[davidmead]

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!

@davidmead

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

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.

[davidmead]

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

[davidmead]

@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!

[davidmead]

@Benjamin And now it’s stopped working again

Seems to be no rhyme or reason

Hi @davidmead ,

Can you please try to reinstall Roon on your Macbook?

Let’s try a fresh database and see if your issues persist:

• Create a Backup of your current database
• Exit out of Roon on the Mac
• Navigate to your Roon Database Location
• Find the folder that says “Roon”
• Rename “Roon” to “Roon_old”
• Reinstall the Roon App from our Downloads Page to generate a new Roon folder
• Verify if the issue persists

Here is the process outlined from a macOS machine:

[davidmead]

Hi @noris.

As stated in my original ticket I did follow those steps originally, but still ran into the issue.

I followed the steps you outlined this morning. Once again the Roon install cannot find the Nucleus.

You can also see I renamed the Roon folder, in Libraries, and the new one is present.

Any help would be appreciated.

Hey @davidmead,

Sorry to hear you only had a connection momentarily! What happens if you select ‘Find my Roon Server’? Are you still unable to locate the Nucleus?

As a next step, can you setup a direct ethernet connection from the Macbook directly to your router and see if you still have issues?

We’ll also want a copy of your Roon logs from the issue Mac - could you please use the directions found here and send over a set of logs to our File Uploader?

Thank you!

[davidmead]

Hi @Benjamin.

I zipped up and sent the Logs folder to you via your FileUploader. Under the name ‘David Mead’.

These were from my MacBook Air.

I cannot connect my MacBook Air via ethernet as I don’t have the dongle I’m afraid.

Roon on my MacBook Air still cannot find the Nucleus server, even after restarting the Nucleus with the latest “listen later” update.

[davidmead]

Also @Benjamin I don’t get the option to ‘Find my Roon Server’. Just 'select a different Roon Server".

Hi @davidmead,

We wanted to check back in on this issue in case you’re still having problems.

MacOS 15.2 included a change to MAC and IP address assignment on WiFi networks. I recommend navigating to your network settings page on this MacOS machine and clicking WiFi → Details. There should be an option to assign a Fixed, instead of a Rotating, WiFi Address.

Also, can you confirm if there’s any change in behavior if you try to press the “Select a different Roon Server” button, nothing shows up at all there? Please let us know if this helps. Thanks!

[davidmead]

Hey @connor

I am now running MacOS 15.3. I did make that change in the settings and while Roon does launch most times I still get the occasional “uh-oh somethings not right” and “waiting for your Roon server”.

Can also confirm “select a different” nothing shows up.

Hey @davidmead,

Thanks for the update! If possible, could you please reproduce the issue and send over a set of Roon logs from the MacBook air? Please use the directions found here and send over a set of logs to our File Uploader?

It may also be worth refreshing your Roon database on the MacBook -

• Create a Backup of your current database
• Exit out of Roon
• Navigate to your Roon Database Location
• Find the folder that says “Roon”
• Rename the “Roon” folder to “Roon_old”
• Reinstall the Roon App from our Downloads Page to generate a new Roon folder
• Verify if the issue persists on a fresh database before restoring the backup

Hi @connor

I’ve been traveling, but I will give this a go when I get back.

[connor]

Hi @davidmead,

Take all the time you need - we will watch for a response and pull diagnostics as soon as you’re back and ready.
