Matter devices always offline after power outage

[ManiacMouse]

Describe the issue you are experiencing

I have two Eve Energy devices connected using Matter. Its been working just fine for about half a year. During a power outage a couple of months ago, I had similar issues with the network being unreachable for the Matter Server, but it was resolved by just restarting HA and my Border-routers and its been working since even after regular updates of HA and the Matter Server addon.

Last night, I unpowered my whole house as that is the only way for me to unpower and reboot my solar panel inverter which was having issues unrelated to this. When starting everything up again, my two Eve Energy devices remain constantly offline and the Matter Server complains about the network being unreachable, but I have not made a single change to my network configuration or HA configuration, I just unpowered everything and then powered everything back on.

I have four Border-routers, three of them are Apple Homepod mini's and the other is a Google Nest Hub. They all show up in the HA Thread integration. If I restart them, they disappear and pop up again so clearly connectivity is there. Both Eve Energy devices are paired directly with HA. The Matter Server does discover the devices on MDNS, but fails to connect to them.

To solve this, I have tried restoring older backups of the Matter Server integration but with no luck. I've restarted HA, the Matter Server, the Eve Energy devices and the Border-routers many times. I have a UniFi based network which is configured according to recommendations with IGMP snooping and mDNS turned off and everything is on the same VLAN. I've even tried disabling all UniFi security features that could potentially block, but still no luck. I even enabled IPv6 on my LAN just cause, why not, but its made no difference either. My HA OS does not acquire an IPv6 address even it says IPv6 is enabled, but I also cannot see any IPv6 support in the /etc configuration files. But either way, things where working just fine without IPv6 on my LAN before so IPv6 should not be the issue here.

What type of installation are you running?

Home Assistant OS

Which operating system are you running on?

Home Assistant Operating System

Which add-on are you reporting an issue with?

Matter Server

What is the version of the add-on?

6.1.2

Steps to reproduce the issue

I don't know how to reproduce it. It was working for half a year, and now it is not. So I guess the steps are:

1. Power off everything
2. Power on everything
