I've been searching ways to debug ongoing issues around matter-over-thread I've been having. I can no longer add devices to HA and the only means I have to add a device is with my iphone which has been impossible to get logs of the pairing events to find out if maybe my ipv6 setup is broken. Does anyone know of some tests/checks I can do to ensure my network is setup correctly?

The frustrating thing is I have devices added to the network already but I cannot add any more 😦

Did you look at your Matter server log? This is the first place to look. Do you have a flat network with all Matter devices in the same VLAN? Which network equipment do you have?

Yeah, flat network all on one vlan

Ok, and what says the Matter server log? Do you see any issues/errors?

There's lots of noise but of the errors I see this seems like it could be related
