Ngnix not forwarding request to gunicorn socket.

Saw in another place an answer that MAY help - not sure. In Django, there’s a ALLOWED_HOSTS configuration parameter which needs to have the domain name. I’m not sure if Flask has that or not - apologies. If it does, check that out.

Hi :)

First off, good job on getting this far. Just FYI, many of the more popular tutorials have versions for different platforms, eg, there is a version of that tutorial for Centos 7 here:

https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-gunicorn-and-nginx-on-centos-7

OK, so in the nginx config, for server_name you put your public Droplet IP? That’s in this section of the tutorial, https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-gunicorn-and-nginx-on-centos-7#configuring-nginx-to-proxy-requests.

At the end of that section there’s a couple of commands to start and enable this config - were you able to run those? If nginx is already running, you may need to restart it like:

sudo systemctl restart nginx

Hope this helps, let us know how it goes.

Heya,

First make sure you’ve added your Droplet’s IP address and your domain name + www.domain.name to your Allowed Hosts in the settings.py file.

Next, you can use this nginx config as an example of how to configure nginx so that it works

server {
    listen 80;
    server_name yourdomain.com www.yourdomain.com;

    # Redirect HTTP to HTTPS (Optional, if using SSL)
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name yourdomain.com www.yourdomain.com;

    # SSL Configuration (Optional, if using SSL)
    ssl_certificate /etc/ssl/certs/yourcert.pem;
    ssl_certificate_key /etc/ssl/private/yourkey.key;

    location / {
        proxy_pass http://127.0.0.1:8000;  # The Gunicorn server
        proxy_set_header Host $host;
        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 $scheme;
    }

    # Static files
    location /static {
        alias /path/to/your/flask/app/static;
    }

    # Log files (Optional)
    access_log /var/log/nginx/yourapp_access.log;
    error_log /var/log/nginx/yourapp_error.log;
}
