504 Gateway Time-out 504 Gateway Time-out nginx

Nginx shows 504 when it does not get any response from PHP backend for long time.

Try increasing timeouts.

A. If you are using PHP-FPM (fastcgi_pass)

location ~ \.php$ {
  fastcgi_pass ... 
  fastcgi_read_timeout 300;
}

B. If you are using proxying (proxy_pass)

server {
...
    proxy_connect_timeout       300;
    proxy_send_timeout          300;
    proxy_read_timeout          300;
    send_timeout                300;
...
}

Tune up to your needs. I think 3min (180 s) is reasonable, but setting it as high as 5 min (300 s) wont break the things and surely will reach PHP backend, or at least max_execution_time set for PHP

in /etc/nginx.conf
(or /etc/nginx/nginx.conf some reddit threads say its in /usr/local/etc/nginx)
or its parts included from main file ( with include /path/to/file directive )

You have to restart nginx after changing its config.
(with nginx -s reload or via your OS services controller)

You can refer to your OS documentation where to find the files and how to restart nginx service.
