Expose local deployment to internet using a domain

Hello, 

I am trying to expose my local creatio instance to public network using a domain. I did all the steps mentioned here - https://academy.creatio.com/docs/8.x/setup-and-administration/on-site-deployment/application-server-on-windows/switch-creatio-website-from-http-to-https

So that I can use Creatio AI locally.

I got a domain and certs(using letsencrypt). 

But the login is not working locally. I can provide more information for debugging.

I am not able to access the app through domain as well.
