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
When did this problem start? Maybe at 1st of september? Do you habe more firewalls but it happens only with one device? Is the cpu load higher than normal on your panorama since this problem startet?
Just in case it is the problem I am aware of try to do a search query in the system logs where you display all logs starting from 08/01/2019 00:00:00 untill 08/31/2019 23:59:59. This query maybe won't show any results but if it is the same problem I had it will take - depending on the amount of logs you normally have per second - something between some minutes and a few hours and evrything will be normal again.
Problem is happening for last 2 months its not with only one firewall, all connected firewalls are disconnected and connecting again.
CPU load is normal not much high.
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.
