Hi Team,

HTTP/1.1 404 object not found

We are seeing this error when the traffic is passing through the Palo. When we bypass palo it works absolutely fine. May i know what could be causing this?

Regards,

@Sanjay_Ramaiah,

That message is coming from some webpage when you try to access it with the PAN in place correct? Is it all websites or just a single website? 

Generally speaking you're likely just not allowing access to whatever the requested resource is. Temporarily override the interzone-default policy so that you're logging denied traffic, and then check your traffic logs to insure that you have policies and routing setup properly to whatever the destination is. 

Chances are high that you have a routing issue when the firewall is installed, or you have a security policy issue and you aren't allowing the traffic.

@BPry Thanks for looking into it. Looks like the decryption policy was the cause for the issue. Change in teh certificate after inspection was causing the issue. After adding a no decrypt rule issue resolved. Thanks again 🙂
