How to fix nginx server returning 302 redirect instead of 200

[Xavier Cardil Coll]

On this setup, there is a server directive listening to port 80 that
returns www to non www and returns 80 to 443.

The second server is Nginx as SSL terminator, so it's an SSL virtual host,
that proxies the request to Varnish, and the last server is the last host
on the chain, that processes and serves back the requests.

Now, when I bypass the chain and do a `curl -v 127.0.0.1:8081` ( this is
the backend vhost, the last in the chain ) I get a 302 redirect instead a
200. This is causing problems on my CMS and also with Varnish communicating
to the backend.

    This is the curl response :

    * Rebuilt URL to: 127.0.0.1:8081/
    * Hostname was NOT found in DNS cache
    *   Trying 127.0.0.1...
    * Connected to 127.0.0.1 (127.0.0.1) port 8081 (#0)
    > GET / HTTP/1.1
    > User-Agent: curl/7.38.0
    > Host: 127.0.0.1:8081
    > Accept: */*
    >
    < HTTP/1.1 302 Found
    * Server nginx/1.9.9 is not blacklisted
    < Server: nginx/1.9.9
    < Date: Sat, 19 Dec 2015 16:04:14 GMT
    < Content-Type: text/html
    < Transfer-Encoding: chunked
    < Connection: keep-alive
    < X-Powered-By: HHVM/3.11.0
    < Vary: Accept-Encoding
    < Location: https://domain.com
    <
    * Connection #0 to host 127.0.0.1 left intact

And this is my nginx configuration :

    server {
        listen 80;
        server_name www.domain.com;
        return 301 $scheme://domain.com$request_uri;
        if ($scheme = http) {
                    return 301 https://$server_name$request_uri;
            }

    }



    server {

    listen 443 default_server ssl http2;

    server_name domain.com;
    access_log  off;
    ssl_certificate /etc/ssl/private/cert_chain.crt;
    ssl_certificate_key /etc/ssl/private/server.key;

    if ($allow = no) {
            return 403;
            }
            if ($bad_referer) {
            return 444;
            }

    location / {
    proxy_pass http://127.0.0.1:8080;
    proxy_set_header X-Real-IP  $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto https;
            proxy_set_header X-Forwarded-Port 443;
            proxy_set_header Host $host;
    proxy_redirect     off;
    proxy_set_header HTTPS "on";
    }
    }

    server {

    listen 127.0.0.1:8081;
    root /var/www/domain.com/wordpress;
            index index.php index.html index.htm;
    server_name domain.com;
    error_log /var/log/nginx/upstream.log info;

            if ($allow = no) {
            return 403;
            }
            if ($bad_referer) {
            return 444;
            }
