Hi @Oblagonte,

This field should have a drop down options.

Do you have latest content updates installed? Are you trying to push this configuration from Panorama or configure it locally on the firewall?

You may also want to check the following KB, there are some useful commands - https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000PMXKCA4

Hi @aleksandar.astardzhiev

It is configure locally on the firewall and content updates was latest. Is there any idea?

Seems like there are limited documentation related to this.

Thanks for your idea

Hey @Oblagonte ,

The third line from the bottom look strange...

- Is there any network device on the path from firewall management to Internet that could apply SSL decryption? If firewall is failing to validate API certificate, it is possible that traffic is being decrypted and certificate is replaced with CA that FW does not expect

Have you checked the link I shared in my previous post?

What output you get from all commands from steps 1,2 and 3? Please hide any sensitive data as customer ID, FQDNs, etc.

Hi All,

We checked the CDL status and found an error "failed to validate server certificate for endpoint api.paloaltonetworks.com"

These errors generally comes when one of the port or fqdns is not allowed in the environment.
https://docs.paloaltonetworks.com/cortex/cortex-data-lake/cortex-data-lake-getting-started/get-started-with-cortex-data-lake/ports-and-fqdns
Further we checked the traffic logs and found port 444 was not allowed and hitting the interzone default rule season end reason was policy deny.
We configured a new security policy rule and allowed the required ports to make the connection between firewall and CDL, in security rule we called a CDL log forwarding profile to forward the log types to the CDL.
We verified and could see live logs started ingesting into the CDL hub.
