Facebook can't validate Let's Encrypt SSL Certificate, why?

My website is https://bhintika.my.id and Facebook can’t validate Let’s Encrypt SSL Certificate so that the SSL version of my web pages can’t be posted on Facebook. They are all rejected by Facebook.

Fortunately Facebook accepts the non-SSL version, instead of unvalidated SSL.

Most likely you need to do this

I assume this is your custom subdomain.
