Hi All, I am trying to add Matter devices to my home assistant. It seems like I'm able to add this to Google home without fault, but when trying to do it via home assistant the following error appears.

Previously I was able to enroll this in Google home, and then link the service across, but I haven't tried that since it's stopped working.

What is incorrect state, is it to do with inability to communicate etc?

Ipv6 DHCP is off, so it should be using link local addresses. Both the home assistant box (VM running HAOS) and the actual plug are getting local ipv6 addresses since DHCP is disabled.

Home assistant can clearly communicate with the plug to a certain degree because it gets half way through commissioning and then breaks.

if matter over thread, do not use link local address as its not routable between home network and thread network. Wifi devices should work with lla because its simply connect to your home network. Just set it to automatic dhcp and dont disable it
