I have successfully managed to install SSL via certbot into my Nginx Docker container,
but after installation, all traffic routed via HTTPS refuses to connect.
curl https://www.example.com or curl https://the_ip_of_server
curl: (7) Failed to connect to example.com port 443 after 9822 ms: Connection refused
~Port 443 is open on the server(AWS Lisghtsail)
curl http://www.example.com

but when curl http://the_ip_of_server
