All matter devices are unavailable over night

The problem

Since latest 2024.10 update, all my matter devices are unavailable.

I don’t change my network configuration since latest update.

Reinstall of Matter Server addon doesn’t help. Adding matter devices fails with this error:

Update: Also after restoring to 2024.9.3, all Matter devices are offline.

All matter devices are Matter over Thread devices (Eve).

I have a Unifi network configure as mentioned here: https://community.home-assistant.io/t/configuration-unifi-for-matter/671315/12

Nothing changed to my configuration, since 2 days over night, all devices are unavailable.

Devices in Apple Home are working well.

I’m seeing the same issue as soon as I restart the Matter Server. Matter Server version is 6.5.1

Update: Clean installed Home Assistant: Same behavior.

Also with latest beta Matter Server addon.

@idominiki what Matter devices did you had connected (make/model, are they connected through Thread border routers? If so, what Thread border routers do you have? I guess Apple, but to get a better picture of your setup, please specify what devices you have and how they are distributed).

I have a Unifi network configure as mentioned here: https://community.home-assistant.io/t/configuration-unifi-for-matter/671315/12

What settings do you use for Multicast Enhancement and Multicase and Broadcast Control currently? Can you try with both disabled?

Devices being unavailable after restart is expected at first, but after setting up the subscription things should slowly become online again. Do your devices stay offline for more than say 10 minutes? If so, can you also describe your setup a bit more in detail (BR, make model, devices, type etc...)

Hi @agners Thanks for answering. For me the problem was the system which runs HAOS: Virtualization Station on QNAP. Whatever happens over night, on a dedicated raspberry pi everything works fine.

I just tested again: IPv6 is disabled for network configuration on my QNAP. HAOS OVA imported to Virtualization Station. Same problem in the Matter Server Addon log:

2024-10-07 20:40:45.889 (Dummy-2) CHIP_ERROR [chip.native.-] src/inet/UDPEndPointImplSockets.cpp:416: OS Error 0x02000065: Network is unreachable at src/controller/SetUpCodePairer.cpp:280

Uh, this could be a IPv6 ND issue, specifically that multicasts don't make it through the bridge or similar. Check and compare the routing tables on the OS shell (ip -6 route).

Depending on how the kernel is on QNAP you might suffer this issue still.

In any case, QNAP is not really a supported virtualization environment.
