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

Hello,

Which model of firewall are you using and what version of PAN-OS are you running on it?

Just curious.

Hi @Venkatesan_radhakrishnan

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.

Regards,

Remo

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.

So did it may be start at 1st August?

If you did not already do so, I recommend to open also a TAC case (in addition to asking the community)

any resolution to this issue. We are also having same issue on Panorama running 8.1.9 version

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

@DuvallDav

I am using PA 220 with PAN OS 9.1.10 and having no issues.

I will recommend you using PAN OS 9.1.10
