Error connection refused for website

My website under the domain returns an error connection refused when accessing via HTTPS on normal internet browsing but accessible when used a VPN. Anyone know how to fix this error? Everything is setup correctly but problem still exists.

The nameservers are also propagated correctly when checking on almost all of the dns checkers.

I am using an AWS lightsail and domain for my website running Ubuntu 18.04 with 32GB of Main Memory and 6GB of RAM.

Attached below are screenshots that shows the website is unavailable on HTTPS without using VPN.!
