Description of Issue

I am reopening a thread that was previously closed. Following the latest update to Roon (which may or may not be the source of the problem) the issue is reappearing.

Roon on my remote macbook pro has stopped displaying a ‘This Mac’ section in the audio setup and no longer sees the external speakers (Kanto Tuks) that are connected via usb to the remote mac.

It’s as though Roon on the Remote MacBook Pro suddenly thinks its running on the Core.

For example, on the screenshot below, the entire section in red, including any option to select the Kanto TUKs or any other Remote ‘This Mac’ option, has now disappeared:

This is what is seen now:

All other applications and system audio continue to play through the TUKs normally.

Rebooting the Core (Mac Mini) as well as the Remote (Macbook Pro) and the TUKs doesn’t help. Nor does deleting the databases on my Remote and reinstalling Roon.

Any help would be greatly appreciated. Thanks!

Do you see anything in settings/about for the remote?

Were there any recent updates on the Mac that might have changed firewall or security settings?
I have seen a few others have this issue and the suggestion was to check security settings, make sure there are exception in place to allow Roon and RAATServer through your firewall, and try turning off VPN, Firewall, antivirus individually and see if it helps.

Thanks. I do see ‘This Mac’ in settings/about for the remote. See screenshot below:

There have been no other system changes. This has always worked fine until a few days ago - seemingly coinciding with the latest update. Firewall and VPN are off.

Have you tried restarting your network? Since you already rebooted core and remote, other than that I can’t think of anything else to try. Maybe @support can help?

[Jordan]

Yes, I have rebooted the network and Roon core and remote - with no luck or change.

Hopefully @support can help, as I’ve gone quiet until we can get this fixed.

Hey @Jordan,

Thanks a lot for connecting with us and sharing the issue you’ve ran into. We’re so sorry about that.

While we haven’t said something right away, our team has investigated your case, and everything seems to look right, except IP addresses: the Core and remote (the machine used as remote) differ. One is 192.168.1.10 and the other 172.27.35.159:920:

Could you please share a little more about your network setup? Are there any details that would help clarify why the Core and remote are not on the same IP subnet?

Thanks

[Jordan]

Beka, thanks so much for the reply. You were on to something…

The Core and remote should have been on the same IP subnet (192…) and I don’t know why the remote would have flipped to 172. The router was not showing different subnets, but it seems to have happened. If you have any thoughts on how this could have occurred, I’d be interested…

In any case, I assigned a static IP address (192.168.1.11) to the remote and rebooted everything – and now the ‘This Mac’ section (with the Kanto TUKs) is back. All seems to be good!

Thank you again.
Jordan

What great news, @Jordan! Thank you so much for looking into the network settings

I’m really glad the issue was resolved. I will pass on the thanks to the QA team who discovered all this.

Enjoy the music
