NGINX Configure Https

I am trying to run my application on http and https. The application renders static htmls along with their css' and js'. I use nginx to serve the pages. I have configured my nginx configuration, but the pages do not get rendered on https.

When I hit http://subdomain.example.com, it works well!

However, when I hit https://subdomain.example.com, I get a CONNECTION_RESET or a CONNECTION_CLOSED error in Chrome.

Below is my configuration:

    server {    listen       80;    server_name  subdomain.example.com;    #charset koi8-r;    #access_log  /var/log/nginx/log/host.access.log  main;    location / {        root   /var/www/html/htmls/;        index  entergmat.html;    }}server{    listen              443 ssl;    ssl                 on;    server_name         subdomain.example.com;    ssl_certificate     /path/to/certificate.crt;    ssl_certificate_key /path/to/certificate.key;#   ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;#   ssl_ciphers         HIGH:!aNULL:!MD5;    keepalive_timeout   70;    location / {        root   /var/www/html/htmls/;        index  entergmat.html;    }}

Request your help on this.

Thanks!
