Image and description is not showing in Facebook

Hi,

I am unable to share my wp posts to facebook. When posting to fb page and groups, it just grabs homepage’s link alone, not post link. For my old posts it working fine. But for new posts, there’s no thumbnail. no meta description.

For eg, My post link is https://www.example.com/samplepost1, When I sharing in fb it shows just https://www.example.com. I dont know why.

I deactvated all plugins, then tried. but no use. (Jetpack shortlink is working fine. with that, I am able to post in FB without any issue.)
