Related posts images are not displaying for all psots

Hi,

I need help from the Jetpack support team!

On my website, thumbnails for related posts are not being displayed for all posts. Half of them have the thumbnail showing, while half have a broken image. I’ve tried clearing cache, uninstalled>reinstalling jetpack, and a few other solutions but still, many images are broken and don’t display.

Do you know any solutions for this?

Thank you.
