Upgraded to IE11 - issues with content blocked because it was not signed

[kennysarmy]

I am testing IE11.

 

When logged on as a test pupil:

 

When I visit this page on our website;

About the School | Balcarras

 

The top two videos are just black boxes and the bottom video states:

 

"content was blocked because it was not signed by a valid security certificate"

 

If I use Google Chrome I get black boxes on the top two videos and a grey box with a smiley face in the bottom placeholder.

 

When I log on as a domain admin: (less filtering)

All three videos work under IE 11 and Chrome.

 

 

However, when I logon to a PC as admin running IE9

The top two videos are just black boxes and the bottom video WORKS!

 

In Google Chrome they all work.....!

Certificate revocation isn't working because of the additional filtering on the student account; newer browsers care about it, older not so much. Watch the proxy log when logged in as a student and you'll probably see connecting requests to certificate authorities being swatted down. A couple I had to add to my whitelists:
