Some images are not importing

Hello,
I’m importing products into WP from several csv feeds and one of them didn’t import some images and I can’t figure out why. The import settings are the same for all feeds.

I test uploaded one with non-functioning images to my hosting created a csv feed in which I put a previously non-functioning product, but with the image I uploaded to my hosting and the image is showing, it works.

Simply when I have the image at my hosting it imports normally, But when I import directly from the official source the image doesn’t work.

For example:

non-functioning images:

ok:

Why do some images display and others don’t when they all have the same source?

I’ve already searched on google what I could, but I don’t know.

Thanks for the advice, help.
