#Matter devices stop working on HA while still available through Apple Home

I added my matter devices (2 locks) via Apple Home app. After they're added, they work perfectly on HA then stop responding.
I see this in the logs:

Happened already weeks ago and changing the batteries fixed the issue. This time, it's not working.
Any idea what I should do?
Thanks in advance.

Hi,
Any hint here?

I can only guess ....Matter Server is getting mDNS advertisements, presumably from an Apple TBR, but Matter Server can't talk directly to the device(s), which could possibly be explained by HA not having an IPv6 route to reach the device. It is usually the TBRs that advertise a route to HA that allows HA to reach the devices. These advertised routes have lifetimes that will eventually expire. So I really don't know if this is actually the case or if it is, then why, but something to look into.
