Panorama Dynamic Updates SSL Connect Error

L0 Member

After upgrading some of our firewall and Panorama to PAN OS 8.x, we cannot push out dynamic updates from Panorama anymore.  We are still able to push out dynamic updates to firewalls running anything below PAN OS 8.x, but nothing within the PAN OS 8.x range.


We verified and are not blocking port 28443 anywhere, but are getting an error when trying to manually push out dynamic updates from Panorama to firewalls running PAN OS 8.x


See screenshot.  Any thoughts?

Hi @Elijah.Putnam


could it be you have secure client communication / Check Server Identity enabled on these devices?

Negative. We do not have this feature enabled on Panorama or the firewalls.

We have same issue with PanOS 8.1.2 

Devices with Pan OS 8.x.x use new application for dynamic updates (paloalto-updates  tcp 28443).

Did this get solved?  If so could you share the solution please?


Nevermind...I've just figured out that the above post regarding the new application and port number is the correct answer. Thanks folks.

Yes, paloalto-updates app solved the issue.
