VM firewalls can not join VM panorama all hosted in AWS cloud

Hello Team,

We are having an issue connecting palo-alto VM firewalls in AWS to the panorama hosted in AWS as well.

connectivity is successful between the firewall and panorama and we are using management port for this traffic.

we ran below command

show netstat all yes numeric-hosts yes numeric-ports yes | match IP

and found the state established on 3978.

when we read ms.log file, we see as below

SC3: failed to get SNI
 -0700 Warning:  sc3_get_current_sc3(sc3_utils.c:182): SC3: failed to get CCN

as per this seems like secure connection issue, but we performed sc3 reset procedure multiple times and also completely removed and re-added the firewall to panorama, but still not connecting.

Below is the complete error or ms.log file message we are seeing

has any body faced similar issue before where firewall is connecting to panorama in aws after performing all the required steps ?Here is ms/log file message

I'm working with a customer who is having the same issue. Migrating from an ESXi hosted Panorama instance to an AWS hosted Panorama instance.

Hello @Jagdeep1

- Could you confirm you followed this procedure: recover-managed-device-connectivity-to-panorama for recovery?

- Could you provide screen shot of logs what happens after log line with "device_registered no"?

- Could you confirm what PAN-OS is running on FW and Panorama?

Kind Regards

Pavel

Hello Everyone,
I am also facing similar problem where our VM firewall's are unable to join to on prem Panorama, it suddenly started after sudden reboot of these devices hosted on kvm, any resolution was found to your problem ?

Had to Re-deploy the panorama. It solved the issue. Not sure what was wrong with initial instance.
