If you are getting “504 Gateway Time-out” errors in a PHP Nginx PHP-FPM environment, review the following settings.
- php.ini:
max_execution_time = 300 - php-fpm.conf:
request_terminate_timeout 300 - nginx.conf:
fastcgi_read_timeout 300
However, if these settings do not resolve the error, you may be able to resolve the problem by setting fastcgi_read_timeout 300 in default.conf instead of nginx.conf.
