Sorry, but to me it’s not so clear on how you expect us to help you. You already say you can’t see port 80 and 443 open through external test sites and you can’t ping your AWS server.

This community is there to help you with (Let’s Encrypt) certificates, with SSL/TLS issues and other stuff related to the HTTPS PKI. To me, this sounds more like a general server management issue, not really related to Let’s Encrypt, SSL/TLS or certificates?

But I could be wrong of course.
