Enabling IGMP snooping / multicast forwarding and rebooting primary Thread Border Router.

Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

  1. In home router Wi-Fi settings, enable IGMP Snooping and disable ‘AP Isolation’.
  2. Power cycle your primary Thread Border Router (Apple TV 4K connected via Gigabit Ethernet).
  3. Power-cycle the unresponsive Matter accessory for 10 seconds to prompt a fresh Thread mesh re-route.

Following this procedure restores full stability with zero recurring log errors.
