Computer's Firewall Setting has Changed

Maybe see if this will help…

Yep, I tried that.   Sonos is already set to accept all incoming connections and I still get the same error.   Any other ideas?

There’s this link too…

Although I would perhaps try uninstalling the App and reinstalling it and connecting it to the ‘existing’ Sonos system and let the App configure the firewall for you.

Thanks for your continued help Ken.   Unfortunately those didn’t work either.   I was hopeful the uninstall/reinstall would work, but no such luck.

I’m really not sure then, as I’m not familiar with the firewall, maybe see if anyone in the Apple/MacOS community can perhaps assist you, or perhaps go onto speak with Sonos Support Staff via this link:

I’m having the same problem. Sonos suddenly refuses to work and throws up this Firewall issue.  But all the Firewall settings on my Mac are fine.  And Sonos is working on my phone.

This is just one more example of the many little ways Sonos keeps coming up with to make me regret I ever bought the system

Hallelujah!     I got it working (it had nothing to do with the Firewall, despite the stupid Sonos popup box) by following the reply I found on a different thread.  Here it is - it worked for me and for someone else who responded, though it didn’t work for everyone - in case it works for you:

Got mine working again by going to System Settings > Privacy & Security > Local Network and toggled Sonos off and then back on. Restarted the Sonos desktop app and now it connects. Weird.

Apple caused this chaos, just like they did years ago when they added this permission to iOS.

Sonos need to update the message in the app, their documents, and their notes to their Support folks to cover this new roadblock Apple threw down.

I’ve been an Apple user for years which includes Mac’s. I have to respectfully 😊 disagree that Apple has set a road block in Mac security privacy center. All that is required is that the Sonos app be given permission to update and make changes in the background. The Mac OS will prompt the EU to do so if desired. One just has to be familiar with how to navigate within System Settings.

I’ve used Windows in the pass and quite often third party software would jack-up the Windows OS as it made changes that really required a bit more EU interaction to properly integrate it.

However, I do agree that Sonos needs to be more proactive regarding what may be required to use Sonos software on a Mac.

Please don’t be an Apple apologist for this one. The idea of the permission is good, but Apple have done a terrible job with it on iOS and now MacOS. Here’s why:

• Apps cannot tell if the option is on or off, to warn the user and generate decent messages for them
• The automatic prompting when an app first tries to do this is unreliable on both platforms, and if the user accidentally dismisses it the first time they have no idea later how to get it back. (See item #1 above)
• The option has three states: never, on and off. There is literally no way to test ‘never’ more than one time per hardware device (on MacOS).
• Sometimes after app, OS or device updates, the setting is lost, and the user is never prompted.

All of this would be workable if #1 was fixed: when the iOS option appeared, devs begged on the forum for Apple to give a way for apps to tell what the setting state was (like many other permission settings), and years later they still haven’t. This is 98% on Apple (and 2% on Sonos for not updating their docs).
