WordPress meta not appearing in Facebook Meta

As there is no open graph meta(og) tag set.

Kindly use some plugin to set that.

It used to appear earlier Now its vanished suddenly. Can u suggest some plugins?

And Facebook Og tags are present:

<!-- Jetpack Open Graph Tags -->
<meta property="og:type" content="website" />
<meta property="og:title" content="Chocozonia" />
<meta property="og:description" content="Best online chocolate store" />
<meta property="og:url" content="https://www.chocozonia.com/" />
<meta property="og:site_name" content="Chocozonia" />
<meta property="og:image" content="https://s0.wp.com/i/blank.jpg" />
<meta property="og:locale" content="en_US" />
<meta name="twitter:card" content="summary" />

Meta tags are present in the source code. You will find jetpack has put its source code.
