Streaming Image from URL to UE4

I’m trying to embed/stream an image from dropbox onto a static Mesh in UE4. The image is in PNG format and i’m using the shared URL of the image. Basically i’m following instructions in this clip. Streaming Textures and Videos in UE4 | Live Training | Unreal Engine Livestream - YouTube
However the image doesn’t come up for me even though I get no error.
I’m suspecting it’s got something to do with the material i’m using for the static mesh that isn’t allowing the stream image to overlay on top of it.
Can someone please assist?
