Users are reporting that webpages are displaying incorrectly or won't fully load after the user selected ‘Continue’ in response to a Warn page being shown.
When opening a webpage, a browser would typically make multiple HTTP requests through the Umbrella proxy. Each request would be independent and would be processed & categorized separately by Umbrella and may match against different policies and rules.
If the webpage being ‘Warned’ is powered by other websites for content like images and advertisements, then these may be categorized differently from the website being ‘Warned’. If these categories are blocked or warned elsewhere in the rules policy, then that content cannot be displayed. If the content blocked or warned is for key parts of the webpage layout, then the page may appear completely unformatted and broken.
To resolve the issue, you will need to identify the blocked or warned requests that are key to allowing the Warned page to display. You can add them to a Destination Allow List to allow them to be accessed, or change the policy which is causing them to be blocked or warned. You can examine your Activity Search and look for URLs with the "Blocked" or "Warned" action to determine which URLs were blocked at the same time which caused the webpage to display incorrectly.
