External Dynamic List is not getting refreshed - HTTP error 302

• When a change or update is done on an existing EDL hosted on an external server, the Firewall is not able to refresh the updated EDL.
• This causes the desired traffic not being processed correctly. 
• As the firewall is not able to refresh the updated EDL, it will use an existing old copy of EDL.

• Palo Alto Networks firewall or Panorama. 
• Supported Pan-OS
• External Dynamic List (EDL)

• The firewall is receiving redirect message from the server.
• This can be seen in the configd logs (less mp-log configd.log) as "HTTP error 302"

1. Redirections (http error 302) are not supported by Palo Alto firewalls on EDL configuration.
2. Reconfigure the Server to ensure no redirects are sent to Palo Alto Firewalls.
