Hello,

I am not sure what is going on. I had a pair of lightbulbs in one bedroom, that were turned off for about a week. Upon turning them back on, they reconnected to wifi without an issue but the bulbs did not "reconnect" to matter. I restarted the matter addon and now half of my previously working bulbs do not seem to reconnect.

Nevermind. I had ipv6 disabled on my network. I enabled it and matter seems to be working again.
