Not sure if I am in a right forum. I have an EC2 instance(ec7-1-33-24-12.compute-1.amazonaws.com) and connected to my domain name(mydomain.com). I was getting a security error on top of the browser hence I tried to install SSL from https://letsencrypt.org/. Once I did that I was unable to access the web page with HTTP and https both. Was not loading page at all.

To resolve this:

1. I uninstalled all the letsencrypt.org SSL configurations/libraries and folders.

Still, I was not able to access my EC2 instance or domain from the browser.

To resolve I have to again:

1. Copies all the files from /var/www.html directory to another folder.
2. Uninstalled HTTPd deleted /var/www folder reinstalled https again
3. Did exactly the same from https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/install-LAMP.html
4. Now again I am unable to access the apache server
5. When I copy the EC2 URL its coping with HTTPS and when I change the HTTPS I am able to see apache server details
6. My own domain is still down, not working at all
7. phpinfo.php page is not working, I am getting a static text from them. I have a current version of PHP with 7.2.

Please help how to resolve this issue, or I have to create a separate EC2 instance and backup all copied files to it.

Thanks!
