Internet Explorer blocked this website from displaying content with security certificate errors

Question

I have a security certificate hosted by a CDN provider. The website is https:www.connect4fitness.com

Navigating to the site in IE gives the following error:

"Internet Explorer blocked this website from displaying content with security certificate errors."

When I pull the site up in firefox or chrome, everything works fine. But I do see a warning about "Mixed content" and "Partially encrypted content" when I probe the certificate details.

All the outbound links on the site are https. It's probably some content injected by the CDN that is triggering the message. But how do I pinpoint the exact part of the webpage that is not being encrypted? I need that information to work with the Tech Support of the CDN company as they are claiming everything is fine.

Are there any tools or techniques that I can use to find out which part of the rendered page received by the browser was NOT encrypted?

Additional information:

Purging the CDN cache resolved the error messages for Firefox and Chrome. IE still complains about mixed content though I do not see any "http" requests going out on the Network tab. Any ideas?

Answer 1

The actual issue that was triggering the mixed content error on IE was a broken link to an included hosted javascript file. The call was https but it did not result in 200 response and that somehow made IE stop issuing further calls as it tried to load the page. I removed this call and then IE loaded the full page without any warnings or errors.
