http to https redirection on nginx - nginx

Question

I have a website running on EC2 machine behind an Amazon ELB.
I have configured SSL on ELB hence its handling http as well as https for me.
All requests on https works perfectly. But I want to force(redirect) http requests to https. For some reason, it does not work
I have added redirect rule in nginx but whenever I enable that rule, the nginx server stops responding.
server {
listen 80;
server_name domain1.com;
gzip on;
gzip_proxied any;
gzip_types text/plain text/xml text/css application/x-javascript;
gzip_vary on;
access_log /var/log/nginx/domain1.access.log;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://127.0.0.1:4000/;
### Redirect http to https ####
if ($http_x_forwarded_proto != "https") {
rewrite ^(.*)$ https://$server_name$1 permanent;
}
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains;";
}
}
Here is the configuration of Load Balancer:
Please help me where I am going wrong with the configuration.
TIA.

Answer 1

Try the following:
server {
listen 80;
listen [::]:80;
server_name domain1.com;
return 301 https://$host$request_uri;
}

Answer 2

I propose this code. Teste on my VPS, but not Amazon ELB
server {
server_name example.com www.example.com;
listen 80;
return 301 https://example.com$request_uri;
}
server {
server_name example.com;
root /home/user/www/example/;
include global.conf;
include php.conf;
include ssl.conf;
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
}
server{
server_name www.example.com;
include ssl.conf;
return 301 https://example.com$request_uri;
ssl_certificate /etc/letsencrypt/live/www.example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/www.example.com/privkey.pem;
}
