ssl certificate or nginx proxy server not working - docker

Question

I have created a domain(domain.com) and subdomain (abc.domain.com), and also generated SSL certificates for both by using letsencrypt. Both the Django projects are hosted on AWS EC2 and created proxy server for them which is as follow:
server {
listen 443 ssl;
server_name example.com;
location / {
proxy_pass https://1.2.3.4:444;
proxy_ssl_server_name on;
proxy_ssl_verify on;
proxy_ssl_certificate /home/domain/fullchain.pem;
proxy_ssl_certificate_key /home/domain/privkey.pem;
}
}
server {
listen 443 ssl;
server_name abc.example.com;
location / {
proxy_pass https://1.2.3.4:445;
proxy_ssl_server_name on;
proxy_ssl_verify on;
proxy_ssl_certificate /home/subdomain/fullchain.pem;
proxy_ssl_certificate_key /home/subdomain/privkey.pem;
}
}
I strats the proxy server and both the projects, starting not giving any problem the problem is that when i enter https://example.com on the browser it is not showing the page, but when i pull domain with port no. https://example.com:444, it starts showing the page. I do not know what I am missing.

In order to make https://example.com work you need to correctly configure Nginx with SSL configuration which include using ssl_certificate and ssl_certificate_key directives as it does not seem that you are using them.
Using proxy_ssl_certificate is for using HTTPS connection between Nginx and the Proxied Server which in your case the django application.
Using ssl_certificate is for using HTTPS connection between the user's browser and Nginx which you need to make https://example.com works as expected
