Share Count is Always 0

Hi,
i am using your plugin for the last few months, it’s working well. The only issue I am facing with Facebook share count.

it is not showing share count for the post, for a few older post I can see the count, but for new posts I tried, it is not increasing it is on 0 no change.

For your reference, I just migrated my website hosting from shared to AWS? Does that affect this plugin function? The domain and everything is share, just changed the hosting.

The page I need help with: [log in to see the link]
