Describe the issue

Roon dropping zones

Describe your network setup

Ethernet cat 6, both Roon server and target device. Additional WiFi devices also disappear. Amplifi mesh router.

More info. iOS client loses connection to server repeatedly. No changes to my network setup which has been the same for 5 years. Running latest build of both iOS client and Roon server. This is a regression.

After restarting iOS client, it finds the server but now all audio zones have disappeared.

Hello @Matt_Levin

Thank you for reaching Roon support.

Starting macOS Sequoia (version 15), has tighter (and more obfuscated) network security settings than preceding MacOS versions.

Can you please navigate to macOS System Settings > Privacy & Security > Local Network, and make sure Roon and Roon Server are allowed.

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

Thanks, I did as you suggested (toggle off/on, reboot). Will monitor.

Matt

Sounds good @Matt_Levin we’ll be monitoring for your reply / results. Thank you! :folded_hands:

Hi @Matt_Levin,

We’re reaching out to see if Zone discovery has stabilized over the last few days after changing these Sequoia settings. Please let us know if you’re having any continued issues.

Where is RoonServer hardwired relative to the mesh nodes serving your endpoints? Do you have any issues with iOS connecting when it’s on the same AP to which the Mac Mini is hardwired?

Amplifi mesh setups sometimes take backend firmware updates that affect band steering and multicast handling. Please try disabling any WiFi Optimization and band/client steering features. Amplifi doesn’t expose multicast settings, but if you have any other network equipment outside of what you have listed, ensure multicast forwarding is enabled.

Thank you!

Zone discovery has not stabilized. Right at this moment my iOS client is seeing no zones. Mac Mini is hardwired to the amplifi router. iPhone is usually on one of the mesh points. Zones directly hardwired to the router are not seen. Zones on same mesh point as iphone are not seen. No recent firmware updates to the Amplifi router. Band steering to 5 Ghz band is on. Router steering is off. None of these settings have changed in years. No other routers. This zone flakiness is new within the past few Roon server updates and/or Sequoia updates. I had been running Roon on Sequoia prior to that with no zone discovery issues.

Hello @Matt_Levin

I think the next step here is to enable some diagnostics on your account so our technical staff can get some more insight into what’s going on here.

However, before I enable this feature, I’d like to ask for your help ensuring we gather the right information.

First, can you please reproduce the issue once more and note the time at which the error occurs. Then respond here with that time, and I’ll make sure we review the diagnostics related to that timestamp.

Hi Vadim,
I will try to reproduce the behavior/bug but it is very sporadic. What is the downside of just turning on the diagnostics?

Matt

Hey @Matt_Levin,

Without a more specific timestamp (date/time/name of track playing) - it’d be similar to trying to find a needle in a haystack, so to speak.

How have things performed over the last few days?

Also, does this happen no matter the endpoint you’re playing music to? For example, if you only play audio from the system output of the Roon remote device you’re using, do you experience the same issues?

Thank you!

Hi @Ben, I get that. I have not used Roon in the past few days. It happens regardless of endpoint. The issue is that I see no endpoints. It is completely independent of track or source.

I will try to use Roon this weekend and see if I can reproduce the bug.

Thanks,

Matt

Hello @Matt_Levin ,

Thanks for letting us know. When you have a chance to reproduce the issue, please let us know the date/time/name of the affected track, and we’ll continue troubleshooting. Thank you!

Just happened. 2021-11-21 20:10 EST. This is NOT track dependent. iPhone is on an amplifi mesh point, wifi 5 Ghz. Mac mini Roon server is wired to the amplifi router.

This happened after I was out all day and then came home. iPhone automatically joined the wifi network.

Matt

Hi. I think this may all be user error. I realized the mac mini was NOT set to wake on network activity. So, I think the times I was seeing no endpoints was because the mini was asleep. I changed the setting to wake on network access and now I see the endpoints from the iOS client. Will monitor and let you know. Sorry for taking up your time.

Matt

Hello @Matt_Levin ,

Thanks for lettting us know regarding the wake on network activity. Yes, please monitor further and let us know how it goes!
