All of a sudden, I am receiving this error. Upgraded to the latest firmware, rebooted, and the network is ok.
Matter installation was attempted at hub boot time but failed. In order to use Matter, you
have to install some software dependencies first. Please check hub's Internet connection
and reboot the hub to try again.
Found the problem: I had wifi turned on, and it connected to a network that didn't allow internet. The strange part was that the latest update downloaded and installed fine. Could the matter update connect to a different server?
