I’m not at home at the moment so I can’t check all appropriate settings in Mac Security/ Privacy. However, make sure there in no VPN running nor a 3rd party antivirus with Firewall. If there is a 3rd party antivirus make sure it sees Sonos as “friendly” regardless of whether or not a firewall is involved.
Thanks for your reply. No VPN or 3rd party antivirus or firewall. It is a nearly new Mac running Sonoma 14.6.1.
When this was first set up late last year it worked so something has changed since then.
Try updating your Mac to Sequoia.
Thank you, that worked. I didn’t know there was an update available, my mac didn’t tell me!
