PAN OS 9.1.7
The following traffic log shows the specific URL
The other traffic log doesn't have the specific URL, and also this log cannot be seen in the url filtering log
Is this a expected behaviors or something wrong with the customer's environment?
First and foremost, PAN-OS 9.1.7 is severely dated. I'd advising your customer to upgrade to 9.1.15-h1.
Lastly the detail that you're giving doesn't really specify how the "Deny All 2020-URL" is actually configured. If the traffic was denied due to URL you'd expect to see the URL recorded in the logs as it is in your first example. If the traffic was denied before the URL was analyzed however, the firewall won't record the URL that the client requested. So from what's been provided and the action being reset-both with no further information provided, it appears as though this is expected behavior and the URL shouldn't be recorded.
