We are having a unexpected behaviour with PA identifying a web:
This web is categorize like "news". We have in our URL profile "continue". But we are seeing that this web is being denied with reason "policy deny". Why PA is not allowing this web?
The URL I posted describes a way to serve the resonse page to users without TLS decryption.
The firewall is able to see the URL - at least the FQDN - in the TLS handshake even without decryption. But by default the firewall is not able to inject the response page into this connection as this is only possible when the firewall sees the actual http traffic. So try the solution in the url and hopefully this will solve the issue for you/your customer.
With almost 100% certainty, this is because of TLS decryption. What pan-os version are you using?
The issue here could be related to the fact that this site already supports TLS1.3 and the firewall somehow does not understand the TLS handshake correctly even if a connection with TLS1.2 is still possible.
Try to configure a decryption exception to check if it then works.
But anyway, in this case I would recommend to open a TAC case.
In this case it is at least related to TLS decryption. Without TLS decryption configured the firewall is not able to inject the continue page and because of that you probably have this traffic log entry when users go directly to the encrypted version of the website.
When the users manually enter http:// then as you wrote the users are able to see the continue page and continue also to the website right?
