nginx redirect http to https domain

My application is running on AWS EC2 instance. I have a domain name using HTTPS from cloudflare. I have added "A record" at cloudflare to EC2 IP address

The following in the Nginx configuration i used

step 1)

  server {    listen 80 default_server;    listen [::]:80 default_server;    server_name inzack.com www.inzack.com;    rewrite ^\/[^\/]+\/(.*) /$1 redirect;    location / {            return 301 https://$server_name$request_uri;    } }server {    listen 443;    server_name inzack.com www.inzack.com;    ssl on;    ssl_certificate  /home/ubuntu/certificates/inzack.crt;    ssl_certificate_key  /home/ubuntu/certificates/inzack.key;    real_ip_header X-Forwarded-For;    set_real_ip_from 127.0.0.1;   location / {    proxy_set_header X-Real-IP $remote_addr;    proxy_pass http://127.0.0.1:5000;    }

}

step 2) sudo nano /etc/nginx/sites-available/inzack.com

The following is the entry in the file:

   upstream inzack.com {      server 127.0.0.1:5000;    }    server {    listen 80;    listen [::]:80;    server_name inzack.com;      location / {        proxy_set_header X-Real-IP $remote_addr;        proxy_set_header X-Forwarder-For $proxy_add_x_forwarded_for;        proxy_set_header Host $http_host;        proxy_set_header X-NginX-Proxy true;        proxy_pass https://inzack.com;        proxy_redirect on;           }       }   

I tried all these links:

http to https redirection on nginx

Node.js + Nginx - What now?

Any help on this would be really great...

Thanksk
