Hi Damian, I'd try running
netdisco-do -D discover -d <ip>
in a terminal to see exactly what netdisco tries to do with the device.
Cheers

Hello,
My Palo Altos are no longer showing up in Netdisco.
They are configured with SNMPv3 and worked at one point.
I can still walk the device from the Netdisco instance, and I've
restarted the services to no avail.
Any advice would be appreciated.
Thank you,
Damian Cleveland
