wordpress image editor broken

Hi,

When I try to edit a moved image (located in S3) to crop, rotate…etc…, then their is a broken image link displayed.

And if I deactivate the wp2cloud plugin and try to edit a newly uploaded image (so this one located on my server), every thing works fine.

Is it a known bug or something special in my configuration ?
