Issue with CDN hosted Images

I am attempting to regenerate thumbnails and finding that many of the images that I have hosted in AWS Cloudfront (using the WP Offloads plugin) are showing up this error:

https://<path to my CDN and filename>.jpg skipped. MimeType is an image, but reports non-displayable

Is this expected behavior here ? Ie. is this plugin not capable of processing images that are hosted on this type of CDN ? I love your plugin but would also love it to be able to handle all of my images.

On a side note, I assume that SVGs are not supported as I see errors for them too?
