Palo Alto Panorama “Scheduled Config Export” Error Code 67

We are using the “Scheduled Config Export” feature of Panorama to backup the configuration to an FTP server internally. However when I run the backup I get the following error:

‘Failed to export config bundle file PANORAMA_20220812.tgz to host XXXXXX.XXXXXXX.XXXXXXX port 21 user PanoramaBackupUser passive-mode yes, error code 67’

We were not able to determine the issue and had to create a case with Palo Alto support. They confirmed that this is an issue with version 10.2.2 of Panorama and has been resolved in version 10.2.3. I upgraded our appliance this morning and now this is working as expected.
