Unable to connect using SSH to the device after setting a master key

• A new master key has been set or master key has been changed.
• After the above step, device access using "SSH" fails.

• Palo Alto Firewalls
• Supported PAN-OS
• Master Key configured

Enabling/configuring master key caused encryption of SSH server key.

1. Run the following command on the Firewall to regenerate SSH keys.

admin@NGFW> debug system ssh-key-reset management

2. In case the encryption is enabled for  High Availability, use the "all" keyword at the end

admin@NGFW> debug system ssh-key-reset all

Note: The command requires a reboot of the device.
