Not working with cloud images

Hello,

I have images stored on Google Cloud.
After installing this plugin, I tried to edit a featured image in a product, but this is not working. Once the WP Paint screen pops up, it’s saying “Loading” and that’s it. Nothing happens after hours waiting. I tried all the scenarios like disable all other plugins, theme change etc. Nothing succesfull.

So, is it correct that this plugin is not working on images stored on Google Cloud?
