Hi Ivan, I am having the same exact problem. Here are all of the things I have done to trouble shoot:
Cycled the power (hard switch)
Connected to the web ui and rebooted.
Cycled the power (web ui)
Reinstalled the operating system (web ui)
Changed location from my media center Eero to the basement Eero at the head end
It seems the device may be having issues connecting back to the Roon “mothership” to check for and grab the firmware update.
