• PANOS-10.2.8 later
• Using Email Scheduler

1. The issue is resolved under PAN-242519 in PAN-OS 10.2.11, 11.0.4 and higher codes
2. Upgrade to the fixed version will resolve the issue.
3. As a workaround use the "Destination Service route" under GUI: Device > Setup > Services > Service Route Configuration > Customize > Destination (and specify the ip address)
