IE9 How to Track "Internet explorer has blocked this website from displaying content with security certificate errors."

Question

I have a website in which IE9 says that "Internet explorer has blocked this website from displaying content with security certificate errors."

I have no idea what mistakes he says, however. Firefox correctly shows that the site is secure and that all content is correctly transmitted through HTTPS. The certificate has not expired. The certificate is a standard certificate without a signature, and the application is placed correctly in the domain, and not an invalid subdomain.

Pressing the show content button that monitors the warning will refresh the page, but when the page loads, it will immediately display a dialog box. By clicking on the contents, rinse and repeat the endless loop.

Why is IE making it so complicated? Can someone tell me how to find the equivalent information that I can from Firefox by clicking on the certificate in the URL bar of Firefox, which allows me to see the addresses of all the / jss / css images on the page, which allows me to verify that they are all https in Firefox

Answer 1

Since the problem is not with Internet Explorer, but with general certificate verification, I was able to debug it using the Chrome console interface (developer tools via F12). The URLs causing the SSL error were specified with a "Resource Failed to load" console error, and the URL was specified.

The Internet Explorer console interface never indicated these errors. Fiddler also did not indicate that there was any error with the certificate (I suppose, because its task is to track the extraction of content, and not to determine what is valid).

Answer 2

Press F12 and look at the console for information on which URL has the problem. Fiddler (www.fiddler2.com) will display a pop-up message about what exactly is wrong with this certificate.

Answer 3

This happens in IE7,8,9 and relates to how IE handles mixed content compared to other browsers.

Message

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

occurs when a page that implements https links in a script is served via http. Chrome and Firefox suppress these mixed content posts.

Possible reasons:

• link to javascript file using http protocol
• link to javascript file that does not exist
• link to javascript file over https but redirect attempt to http
• insert javascript links at runtime.

IE users seem to be using this message on sites like facebook, so many will click and continue with it.

Answer 4

You should see:

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

While I can imagine, IE is probably complaining about content being downloaded via JavaScript. If the same content (image or the like) loaded with a regular html request (for example, while loading the first page) probably does not bother you.
