Slideshare Block and Private Slides with Secret links

Hello,
I have an issue with the SlideShare Block, When I use it with public Slide files it works just fine, However, my client required some private slide files, this option is provided by SlideShare through a secret link. It seems that the SlideShare block doesn't read the slides from the secret link provided by SlideShare.

I uploaded a test slide file and made it public and it worked, but when I change it to private and change the normal link into the secret link provided by slideshare it doesn't show the slide att all, its just telling me its being loaded. below is some screenshots..

NOTE: I noticed the letter "s" added after the "http" and removed it.. problem still exist.
