Hi,
I understand that 'Zero Touch' triggers the upgrading, but that doesn't explain where/how the device tries to fetch an update.
Certainly, there is no local server on our network to provide it, so presumably it comes via the internet, which raises potential issues as we have a VERY tight config on the edge firewalls, and would need to allow special access unless it uses http on default port 80.
