Images not displaying when CDN active

I have a number of images using single image, images carousel and how it helps content from WP Bakery that are not displaying on the site. They show up fine in the editor but not in a browser.

Images that are part of revolution slider are all fine.

If I disable the CDN then everything works as well. I can’t see any errors related to this in the chrome dev console either.

Any ideas where to start looking?
