SONOS Update and Firewall Issues

I too have this issue after updating to Sequoia 15.2. 

Same message whether Firewall is on or off. (sonos is already enabled)

Tried local network but Sonos not there (the Sonos 1 controller is, but not Sonos 2) How do I add an application to the local network?

Thanks so much

 Peter_254 you absolute chuffing legend! I’ve been losing my mind with this issue! Thank you. :-) 

I am still having ongoing Firewall issues. I have repeatedly checked the Firewall settings and SONOS is is set to “Allow all incoming connections”. I have reset the controller, removed and reinstalled the controller for the MacBook Air, reset the router. SONOS controllers on all handheld devices work perfectly. Only the MacBook Air controller has issues.

If I remember correctly, and I’m not on my Mac right now, the updater is a separate application than ‘Sonos’. Have you opened your firewall to both?

Yes, the FW is updated to allow all incoming connections on both, but still not working. Thank you for the suggestion.

Odd. I suspect you may need to call Sonos Support directly to discuss it.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

There is apparently a bug in the system at the moment.
I have had the SONOS App on my Mac for a very long time and it has worked perfectly.
Now when I opened it it came up with a firewall error.

Tried resetting the App but that didn't work.
Then I deleted the App, restarted my Mac and installed Sonos again. When I opened the SONOS App it asked for permission, I said yes.
Chose connect to existing system and now it works again.

“Local network” permission is a new feature in MacOS, and it is implemented as poorly as it was on iOS, Its state is often wrong, it often forgets the state after an update, and Sonos don’t bother to detect this specific condition to give a decent error message.

SONOS app on my Mac has stopped working too.  I have completely disabled the firewall and I still get “NOT CONNECTED” error.  

YES I’ve tried all of these:

• re-started router and all SONOS devices
• deleted and re-installed SONOS app
• deleted, power cycled, re-installed SONOS app
• deleted, disabled firewall, re-installed SONOS app
• deleted, disabled firewall, re-installed, re-enabled firewall 

And YES, SONOS is set to allow incoming connections on the firewall settings.

Working fine but laggy on my iPhone (as is normal these days).  It literally just took 5 seconds to skip one track forwards.

I’m curious, what did Sonos Support say, when you called them directly to discuss it?
