Description

This article describes a condition where web pages fail to load or load partially after an upgrade when UTM Web Filtering (WF) is enabled on SRX devices.

Symptoms

Certain websites do not load completely or fail to load
Some websites may load partially while others work as expected

Solution

When Web Filtering is configured with site reputation, access to certain underlying URLs (such as embedded content, scripts, or third-party resources) may be blocked if they are assigned a low reputation score. This can result in incomplete or failed page loads.
 
 

To validate and resolve the issue, review the site reputation configuration applied through Web Filtering.

Test by removing or modifying the site reputation enforcement for the affected URLs or categories. If disabling this action restores proper website functionality, it confirms that site reputation filtering is causing the issue.

Adjust the policy accordingly to allow required content while maintaining appropriate security controls.
