Django - Gunicorn/Nginx - 502 Bad Gateway

Question

Need Help on 502 Bad Gateway ngnix/1.10.3

I have configured my Django application using Nginx/Gunicorn. It was running fine until I made some changes to the code and reloaded the server.

FYI: My settings.py has ALLOWED_HOSTS = ['*']

Error Logs :

Update 1 :

This is my nginx config. Is there any issue with this?

/etc/nginx/sites-available/MySite

server {
    listen 80;
    server_name 18.191.255.247;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/ubuntu/www/MySite;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix://home/ubuntu/www/MySite/MySite.sock;
    }
}

How do i verify nginx daemon permission to the project folder (//unix://home/ubuntu/www/MySite)

Answer 1

Try manually setting the proxy pass URL to the port gunicorn is running the project on the server like:

location / {
                proxy_pass         http://localhost:8000;
                proxy_redirect     off;
                proxy_set_header   Host              $http_host;
                proxy_set_header   X-Real-IP         $remote_addr;
                proxy_set_header   X-Forwarded-For   $proxy_add_x_forwarded_for;
                proxy_connect_timeout 500;
                proxy_read_timeout 600;
        }
