I added ZBT-2 to my HA OS install that's running in a Proxmox VM. Following the guide here (https://support.nabucasa.com/hc/en-us/articles/31347105826077-Forming-a-new-Thread-network-with-Home-Assistant-Connect-ZBT-2) I tried to set a preferred Thread network so I can start connecting Thread devices. But I don't have the option to do that:

I'm not sure what caused this, but the network name changed:

#

I still have no option to make this network preferred or import credentials etc

Maybe a cache issue?

I think I figured it out, I added the ZBT-2 as a usb device in proxmox, when passing through the full usb port and rebooting the HA VM the ha-thread-0f20 network is preferred

#

However, I can't connect a matter device on my android phone

#

I get through the dialog where I scan the QR code then it always says No Wi-Fi connection even though I'm on a wifi network that can communicate with my HA instance and access the internet

#

My phone has IPv6 addresses assigned as well
