Update Remote Firewalls from Panorama Fails

[Jody_Whitlock]

Got a bunch of firewalls, and anytime I try to do an install of software from Panorama, I get errors along the lines of "Failed to download PanOS_xxxx-n.n.n.  Download error: Couldn't connect to server"
If I go to the firewall appliances themselves, I can download and install without an issue.  The firewalls have no NAT or anything between them and the Panorama appliance, except in a few cases they are going over an IPSec tunnel that is terminated on our main PA HA pair.

For troubleshooting, I have a new pair of PA-3250's that are on the same network as the Panorama appliance, no router or anything between them and the Panorama appliance.  I only have the management interface connected at this time, but like I said, I can go to the firewall themselves and perform an update.  Also, pushing templates to the firewalls is no problem at all, so the communication chain between firewall(s) and Panorama is there without issue.

I'm lost.  
Panorama version 10.0.7 in a virtual appliance.

Thank you for the post @Jody_Whitlock 

- Are you facing the same issue when you install application package to Firewall?

- Could you take a packet capture from management interface (Assuming this interface is used for deployment) of Panorama to see Panorama is initiating the file upload?

- Could you try to delete existing image that was downloaded in Panorama, then click: "Check Now", then download image again.

Kind Regards

@Jody_Whitlock,

Did this ever work for you in the past? Do you see traffic originating from the firewall to Panorama on tcp/28443?
