I have over 60 Matter devices that I’ve successfully paired in the past via Hubitat, SmartThings, and HA.
All was great until recently. Now suddenly I can no longer pair any Matter devices on any of my hubs. It fails with both Android and iPhone pairing attempts.
I put my phone on the IoT wireless network, I initiate pairing on the device, scan the QR code, and then it times out looking for the device.
It doesn’t make any difference what the hub is, or the phone type.
The only thing I’ve recently added to my network is a SLZB-MR4U that I configured with HA, but I don’t have any devices to pair with it, so haven’t tested it yet, but I’m not sure how that could affect, say pairing with Hubitat for example.
So this isn’t my first rodeo, I’ve successfully paired dozens of devices in the past.
I have even tried re-sharing existing paired devices between Hubitat and HA, using share codes, and those all fail as well.
I don’t see anyting in the HA Matter logs that’s helpful.
I have Googled everything I can come up with on Matter pairing failures and nothing has helped.
So what has gone so catagorically wrong that I can’t pair any device, using Android or IOS, to any hub type that I have?
I am running HA OS on a Proxmox VM.
