GET http://ift.tt/1v90HKj ... error in console

Hi I am getting this error GET http://ift.tt/1v90HKl 403 (Forbidden)

this error in browsers console in all of my nodejs app. I don't know where is this coming from since I have not added any get route for this. What is causing this? I did find in folder using sublime for this and there is no result for cl4appf in my code base. It is even giving me an error of mixed content and breaking my entire site.

Any help would be appriciated.
