At the risk of cross posting from a thread I created a week or so ago, I’m also trying to get Matter to work on my Unifi network.
I think I have everything setup correctly however my Matter addon is telling me it has no connection to the network and as such, device pairing fails.
Matter addon error log:
(Dummy-2) CHIP_ERROR [chip.native.DIS] Failed to advertise records: src/inet/UDPEndPointImplSockets.cpp:417: OS Error 0x02000065: Network is unreachable
I have spent hours trying to get this to work but still have that connection issue. I figure its a firewall rule …maybe, but can’t see anything that would block it.
My HA server, Matter over Thread radio and phone are all on the same VLAN, IPv6 enabled (including on the HA server) and IPv6 addresses are being allocated.
mDNS on, IGMP snooping off.
I’ve run out of things to test. Any more tips?
EDIT: All sorted. . I had to add an additional ‘allow’ rule in the UDM firewall.
