Always offline for Google Home

[markhike]

I have tried many things including creating a Goggle dev registration, but my devices always show offline on my Google Home after I brought them in through the Matter Hub. My Apple Home can see them and control them, but Google Home is my main control center for all devices (besides Home Assistant of course). Most of my devices I can control via Google Home. Just a few Zigbee2MQTT devices I want to bring in.
Any suggestion would be appreciated to solve this problem.

Debug log needed

debug log attached

[Apollon77]

it is just an Info loglevel log and not Debug. The log shows that commissioning works but when the hub tries to send subscription updates these seemes not to be ack'ed by the controller. But for details I need a Debug log to see the actual traffic flow

Thanks for looking into it. I turned on the debug in the middle. The bottom portion of the log is at debug level (after 2025-03-24 18:20)

Just an update. Found the cause was IPv6 settings of my router. After changing the assigned type from DHCPv6 to SLAAC, the problem was solved. Wondering why it didn't affect Apple Home app.
