Django-Hosts Routing issue in Production

[bobozar]

Django-hosts is working perfectly fine on my development server. But it's not working fine on the production server. when I visit m.example.com it will redirect me to example.com.

I have one project with different apps. I only want the subdomain to make use of mravmomentapp.

E.g

project name: mrav
apps under: mrav/moneapp
                   mrav/mtwoapp
                   mrav/mravmomentapp

My stack is nginx, wsgi, gunicorn.

I placed the hosts.py in mrav/hosts.py

In my hosts.py

if socket.gethostname()=="AM-PC":
    host_patterns = patterns('',
            host(r'examplelocal.com:8000', mrav_base_settings.ROOT_URLCONF, name='www'),
        host(r'm.examplelocal.com:8000', 'mravmomentapp.urls', name='m'),
    )
 ###use this settings in production
else: 
      host_patterns = patterns('',
           host(r'example.com', mrav_base_settings.ROOT_URLCONF, name='www'),
        host(r'm.example.com', 'mravmomentapp.urls', name='m'),
      )

In my mravmomentapp.urls I have

     urlpatterns =[
           url(r'^$', mo_views.home_page, name='home_page'),  #homepage for subdomain  m.example.com 	
         ]

in my nginx.conf

    server {
         listen 80;
         listen [::]:80;
         server_name example.com www.example.com *.example.com m.example.com;
         return 301 https://$server_name$request_uri;
   }


    server {
           listen 443 ssl http2;
           listen [::]:443 ssl http2;
            server_name example.com www.example.com;
             index  index.html index.htm index.php;
            include snippets/ssl-example.com.conf;
             include snippets/ssl-params.conf;

          location / {
                include proxy_params;
                proxy_pass http://mrav_app_server;
         }

           #othersettings

    }

I also created an A host file in my DNS and added my IP ADDRESS to it.

What am I missing?

Fixed. I created another server in nginx.
