Can anyone help me with this?

Matter on anything other than HAOS or HA Supervised is pretty much a alpha release.

I have no clue what is wrong with your setup, but you need for sure a working IPv6 network (a public IPv6 IP is not needed. Just a fe80, which is auto-generated) and you need to make sure that HA supervisor have full control of the docker management.

I think this is the problem.
Doing a little research to try and help out… the Matter AddOn and (probably a few other AddOns as well) rely on calling a Supervisor API to get the primary network interface.

So most likely its a Supervisor problem, or perhaps OS-Agent. It looks like you are running an “HA Supervised” installation (which I know very little about), and here are the requirements. The one thing that stands out, is that Debian Linux 11 is no longer supported.

Thanks for the advice!
It was ultimately the IPv6 setting of the Raspberry Pi. I reinstalled the Home Assistant OS and since then Matter has been running without any problems.

I have the same problem after restoring an update on a new RP5.

Could you please specify exactly what steps I should take in order to solve the problem? Just reinstall Home Assistant OS completely? Or could the issue be linked to the backup coming from a RP3 originally?

Thanks!
