Firewall not connecting to Panorama

[AdamHP]

Hello I have new deployed Panorama and new PA-440 Firewall.

I setup Panorama with all basic settings like IP address/netmask, default GW, DNS, it has license assigned.

Next I generated AuthKey for the firewalls with validity for 10 days and without SN specified. 

PA-440 is in remote location and has a basic WAN setup and IPSec VPN to my datacenter where panorama is. 

It has a vlan interface setup in my internal zone and set as source for every service.

I am able to ping Panorama from the PA-440 so network over VPN is working.

When I setup Panorama IP with Auth Key on the firewall and add Firewall on panorama by the Serial Number I still see PA-440 in panorama as Disconnected.

I checked the DataCenter firewall where IPSec is terminated and I can''t see in logs any blocked traffic in between these two.

Port 3978 for Panorama  is enabled in security rules and I can see some ssl traffic is passing in Datacenter over this port.

Is there something else I forgott to setup or something else I need to check in order to be able to manage this Firewall by Panorama?

Made my day ! One PA-3220 was suddenly unable to connect to our PRA-25 after downgrading it from 10.2.3 to 10.2.2.h2 and this solved it
