I rebooted one and after a few minutes it's online. Looks like you need
to remove the usb power for a few seconds and plug it back in. Good
luck, going to reboot my last one. FYI I did not reset any of my
devices.
Just checked and one is back on line. Not sure when it happened as it
was Monday when I first had the certificate problem and just looked
now.Other two are grayed out an I have not touched them. Only thing I
did to the one working was reboot it prior...
