Why is NGINX giving 504 gateway timeout error?

My NGINX conf is-

server {
    listen 80;
    server_name site.com ;

    location / {
        include proxy_params;
        proxy_pass http://0.0.0.0:8000;

    }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/site.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/site.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}

I am running a Flask app on Gunicorn on Port 8000. When I try to access my site, I get a 504 Gateway Time-out nginx/1.14.0 (Ubuntu).

In the error.log , it says-

 upstream timed out (110: Connection timed out) while connecting to upstream, client:myip server: site.com, request: "GET / HTTP/1.1", upstream: "http://0.0.0.0:8000/", host: "mysite.com"

Suggest to keep like below values, which could resolve the timeout issue.

proxy_connect_timeout   300;
proxy_send_timeout      300;
proxy_read_timeout      300;

You have some errors in your config.

  • You cannot have one server who is listening on multiple ports.
  • You should not write 0.0.0.0:8000, but try 127.0.0.1:8000 instead

Also I dont understand why you include proxy params, just delete that line.

Here is an example of what you could do.

server {
        server_name site.com www.site.com;
        location / {
                proxy_pass http://127.0.0.1:8000/;
        }
        listen [::]:443 ssl; # managed by Certbot
        listen 443 ssl; # managed by Certbot
        ssl_certificate /etc/letsencrypt/live/site.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/site.com/privkey.pem;
        include /etc/letsencrypt/options-ssl-nginx.conf;
        ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
}
server {
        if ($host = www.site.com) {
                return 301 https://$host$request_uri;
        }
        if ($host = site.com) {
                return 301 https://$host$request_uri;
        }
        listen 80;
        listen [::]:80;
        server_name site.com www.site.com;
        return 404;
}

Good Luck :-)
