No image when share on facebook from site. Why?

Question

Facebook

Hello. There is an image written in the meta, but when you make a share from the site, there is no image.

<meta property="og:image" content="https://cdn.themag.uz/2017/03/preview_iroda-tulyaganova.jpg" />

I tried to look through the facebook debug, it sees all the tags, but an error appears [The URL specified for og:image https://cdn.themag.uz/2017/03/preview_iroda-tulyag... cannot be processed as an image. The image may be corrupted or not in a valid format.] Link Although the image is available through a direct link and opens normally. And so on the whole site.
I don't understand what could be the problem.

Answer 1

Everything became ok when I removed the AAAA record for the subdomain.

Answer 2

Is everything ok?
Anyway it works for me
