Facebook sharing just stopped working.

Hi. Like 2 days ago, I notice that my views from Facebook have dropped so much, I then took time to check why that happened. I then found out that all my post I have made in the past days have not been shared on Facebook. I check my jetpack auto publicize to see if my Facebook account is properly connected, they are all connected but none of my post are shared on Facebook.

I needed help with this pls. If anyone can help.
