Nginx + PHP-Fpm 7.1 - 504 Gateway Time-Out

Nginx + PHP-FPM 7.1 - 504 Gateway Time-out

The question is probably why does your backend take so long to respond? Not sure about your usecase but normally it's not user-friendly to wait to long for a response.

To answer your question:

I found this link: https://easyengine.io/tutorials/php/increase-script-execution-time/

Add in /etc/php5/fpm/php.ini

max_execution_time = 300

Set in /etc/php5/fpm/pool.d/www.conf

request_terminate_timeout = 300

Set in /etc/nginx/nginx.conf

http {
 #... 
 fastcgi_read_timeout 300;  
 #... 
}

And in your config:

location ~ \.php$ { 
 include /etc/nginx/fastcgi_params; 
 fastcgi_pass unix:/var/run/php5-fpm.sock; 
 fastcgi_read_timeout 300; 
}

And reload services

service php5-fpm reload 
service nginx reload

I almost completely gave up on this! However at the last minute I came up with the answer.

The servers are on Amazon AWS behind a load balancer. The load balancer had the idle-timeout attribute set at 60 seconds. Changing this setting fixed the problem!!

Looks like you need to increase fastcgi_read_timeout in your nginx configuration.
