Hi all.  I an trying to demo OpManager w/ OpUtils add-on.  I have added one of our location's palo alto firewall as a dhcp server, since it is running dhcp.  I have OpManger configured with REST API and my login credentials.  It scans, and says successful, but does not return any results.  No scopes are discovered or anything.  The firmware of the firewall is 9.1.7.  Am I missing something else?
