Have you, by any chance, took a screenshot on iOS device, and then cropped it using "Photos", and try to upload it?

If yes - then it won't work, because iOS is not actually saving cropped image, it saves image along with history of edits, so it is not "real" graphical file.

You might crop it using another app, like "Snapseed" or "Crop for free", and upload.
