Nginx serving content from the wrong "virtual host" while accessing with https

I have a server running both Nginx and Apache in a proxy setup, Nginx serves the static content and Apache the dynamic content which works really well.

This setup is currently hosting two versions of the same site, lets call them production.com and staging.com.

I've just finished setting up the production.com site using SSL which also works very well, but discovered that if I were to browse to staging.com using SSL as well, I'd get served the content of production.com's web root, which obviously is wrong.

I was told to use a default handler for both SSL and non-SSL, which would eliminate this behavior, but that's where I'm having trouble.

Right now I have this configuration included in nginx.conf

default_80.conf
server {
    listen 80;
    server_name "";
    return 444;
}
default_443.conf
server {
    listen 443 default_server ssl;
    server_name "";
    return 444;
}
staging.com.conf
server {

    listen 80;
    server_name staging.com;
    access_log /var/log/nginx/staging.com.log;

    # static content folders
    location ^~ /(images|css|js) {
            root /var/www/staging.com/current;
            access_log /var/log/nginx/staging.com.static.log;
    }

    # static content files
    location ~* \.(js|css|rdf|xml|ico|txt|jpg|gif|png|jpeg)$ {
            root /var/www/staging.com/current;
            access_log /var/log/nginx/staging.com.static.log;
    }

    # proxy the rest to apache
    location / {

        proxy_pass         http://127.0.0.1:8080/;
        proxy_redirect     off;

        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;

        client_max_body_size       10m;
        client_body_buffer_size    128k;

        proxy_connect_timeout      90;
        proxy_send_timeout         90;
        proxy_read_timeout         90;

        proxy_buffer_size          4k;
        proxy_buffers              4 32k;
        proxy_busy_buffers_size    64k;
        proxy_temp_file_write_size 64k;
    }
}
production.com.conf
server {

    listen 80;
    server_name production.com;
    rewrite ^       https://$server_name$request_uri? permanent;
}

server {

    listen 443 ssl;
    server_name production.com;
    access_log /var/log/nginx/production.com.log;

    ssl_certificate /etc/httpd/conf.d/SSL/ev.crt;
    ssl_certificate_key /etc/httpd/conf.d/SSL/server.key;
    keepalive_timeout 60;

    # static content folders
    location ^~ /(images|css|js) {
            root /var/www/production.com/current;
            access_log /var/log/nginx/production.com.static.log;
    }

    # static content files
    location ~* \.(js|css|rdf|xml|ico|txt|jpg|gif|png|jpeg)$ {
            root /var/www/production.com/current;
            access_log /var/log/nginx/production.com.static.log;
    }

    # proxy the rest to apache
    location / {

        # proxy settings
        proxy_pass         http://127.0.0.1:8080/;
        proxy_redirect     off;

        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;

        client_max_body_size       10m;
        client_body_buffer_size    128k;

        proxy_connect_timeout      90;
        proxy_send_timeout         90;
        proxy_read_timeout         90;

        proxy_buffer_size          4k;
        proxy_buffers              4 32k;
        proxy_busy_buffers_size    64k;
        proxy_temp_file_write_size 64k;
    }

}

This settings kills all kind of SSL access to any of the two sites, and if I remove the "default_server" directive from default_443.conf instead it works for both sites.

So the question beeing, how do I turn off SSL access (https://staging.com returns 444) for staging.com and enables it on production.com?

First, confirm that your version of Nginx supports SNI in case you're using one of those weird distros (you should see TLS SNI support enabled at the top):

nginx -V

I have posted the setup below, here are the results on my box (/var/www/production/index.html contains PRODUCTION and /var/www/staging/index.html, STAGING)

http://192.168.56.101 connection reset (444)
https://192.168.56.101 connection reset (444)
http://staging.example.com STAGING
https://staging.example.com redirection to http
http://production.example.com redirection to https
https://production.example.com PRODUCTION

For reference, I used the stable version of nginx from the debian repositories (0.7.67), but I have a very similar setup on 1.0.something that works almost exactly the same. If you can't get it to work, let us know your exact version please.

In your case, you'll probably want to change both defaults to default_server. You might also want to make the rewrite permanent, and maybe change it to a return 301 if your nginx version allows it.
