Serve multiple Django applications with Nginx and Gunicorn using multiple domains

Heya,

there are a couple of possibilities on the origin of the error,

You have not showed what you have inside your Django settings.py file, but I assume you have not configured the ALLOWED_HOSTS variable as you should have. This is how it should look like:

ALLOWED_HOSTS = [
    'subdomain.domain.com'
]

Also, make sure to restart the Nginx service after doing so. The settings file is loaded to memory, so if you make changes to it, you need to restart the server.

systemctl restart gunicorn and systemctl restart nginx

Hi there,

It sounds like that your Nginx configuration might be the issue if it is serving the contents of only one of the applications.

Can you share both of the Nginx server blocks that you have for each of the two websites? You need to make sure that the reverse proxy rules for each of the sites is pointing to the correct web socket.

Also, can you verify that both of the Gunicorn services are up and running?

Would you mind also sharing the ALLOWED_HOSTS definition for each site as well?

Best,

Bobby

Thank you all, I was able to fix it by redirecting

www.subdomain.example.com to subdomain.example.com 

I used this tut here https://www.digitalocean.com/community/tutorials/how-to-redirect-www-to-non-www-with-nginx-on-ubuntu-14-04#configure-nginx-redirect
