The shared link of my website in facebook is redirected to 404

I have a website with videos in it. and when I share a video on a facebook page,

the link to the website goes to 404

for example my shared link http://ift.tt/1DTbO9q

the link redirects to http://ift.tt/1A2DACW

I also have meta tags and when I use the debugger It doesn't see any of them. Please help!
