LinkedIn not picking up og:image from wordpress

Question

I have a word press website, and when I share a blog on social media, all social media pulls up the thumbnails except Linkedin.

I have used the open graph tags perfectly. What could be wrong?

<meta property="og:title" content="<?php the_title(); ?>" /><meta property="og:description" content="<?php the_content();?>" /><meta property="og:type" content="post" /><meta property="og:image" content="https://www.intellectyx.com/blog/wp-content/uploads/2017/03/Analytics-400x225.jpg" />
