Panorama and Firewall frequent disconnection

Hi Team,


I'm facing issue where firewall and Panorama keeping disconnected every minute. It is getting connected and disconnecting.


This happens within a minute, I have checked the reachability is fine between panoraman and firewall and port is open.


I'm seeing in system logs TLS session disconnected not sure but again it is connecting.


PAN OS 8.1.8

M-100 series appliance


This happens will all my managed devices with Panorama, Also important I have some firewall in same network of Panorama which is also having issue.


Any help in this issue will be greatful

I had the same issues with PanOS 8.1.10.

Issue started occurring some hours after upgrade to 8.1.10, and resolved itself without measures taken after a few days.

Multiple hardware types (PA-200 up to PA-5050) were involved, even when the firewall and Panorama were in the same data center.


TAC mentioned that it might be related to the upgrade. In case this problem occurs again, this packet captures between firewalls and Panorama should be set up and the ms-log should be viewed.


Hope this information will help progress similar cases.


We have M100 and Firewalls  running same version 8.1.9  no issues.

We have 5050,5220,3220,3020,850, firewalls no issues.


Try to downgrade the PAN OS to 8.1.9 see if this helps.


Is there any solution for this issue?, is happening to us using version 8.1.18, migrated to 9.0.12 and right now we are in version 9.1.6 and we have the same issue.

I'm also experiencing the same issue. Version 9.0.9 on a PA-220.
I've check routing and switching and all look good, so I'm starting to look inwards to the PA
