Same issue for me, I’ve got two of the White Series Canopy Modules and they’ll randomly go offline until I flip the breaker. It sounds the dimmer switches already got the fix for White Series dropping thread connectivity, it’d be nice if we could at least get a beta version with just that portion of the fixes for the Canopy module. For network setup, I’ve got Home Assistant hosting the two addons for OpenThread Border Router, and the Matter Server, and then I’ve got a full Unifi network setup. My ISP does NOT provide IPv6 to my home, however I’ve set up the network that Home Assistant is on (and the network I was connected to with my Samsung S24 when I commissioned the canopy module) configured to define a static address, and then am leveraging DHCPv6 with a range of ::2 to ::7d1 (Router Advertisement is enabled, and RA Priority is set to High, as well as Allow SLAAC is enabled). UDM Pro is on 4.4.6, and Unifi Network is on 10.0.160
