URL filtering response pages may not display for various reasons, including:
- SSL/TLS handshake inspections are enabled.
- The website was blocked during the inspection of an SSL/TLS handshake. URL
filtering response pages do not display in this case because the firewall resets
the HTTPS connection.
- The website uses the HTTPS protocol or contains content served over HTTPS (such
as ads) but the website or URL category was not decrypted.
- The custom response page is larger than the maximum supported size.
Use the following steps as a starting point for troubleshooting a URL filtering
response page that fails to display. If the problem persists, contact Palo Alto
Networks support.
If the above steps fail to correct the issue, contact Palo Alto Networks support.
Additional troubleshooting may be necessary to pinpoint the issue. For example,
analyzing the traffic through a packet capture (pcap) tool alongside support may be
helpful if a response page fails to function for some web pages but works for
others.
