On September 30th, Let's Encrypt Root SSL expired.
Any systems that were using Let's Encrypt SSL and were not using the updated version of the underlying Operating System started having problems in SSL handshaking with the third-party platforms.
When you see the SSL on your website, it will appear just fine. But it is not the actual certificate that you see on your browser that is creating the problem but the root SSL is broken on the old Operating Systems.
This issue appears when the sender who is sending the webhook does not have the updated operating system which in turn leads to not having the updated Root SSL registry and the receiver also has the Let's Encrypt SSL.
The solution to this problem is simple, you just have to contact your hosting provider and tell them that you are facing the Let's Encrypt Root SSL issue during the API calls from your platform.
Almost all major hosting companies are now deploying or have deployed the update.
Here is the same issue been posted on our forum and it got fixed when the CloudWays team updated the root SSL registry.
Hello, I am trying to send data (new posts) from Wordpress to Facebook but, even if I create new posts, Pabbly doesn't receive the data. I have already done all the things written in description (plugin, settings, etc..) Thanks

Please Note: Pabbly Connect Web server uses the latest version of the Operating System and has all the latest root certificates installed.
As soon as you get the update done from your hosting provider, your webhooks will start to work just fine.
