upload from post body doesn’t work

Hello,

1. tried to upload a product from CSV that contain an image in the description but the plugin didn’t upload it but featured an image from the same source… I didn’t face any issues.
2. does this source block me or it is something in the plugin? as it does not work with featured image upload – https://d3m9l0v76dty0.cloudfront.net/system/photos/6067070/large/80cc0af2085bf9d5735b91fc0dfc3292.jpg
