Hi,

what is your value of max_execution_time in php.ini?

If you are running php-fpm there might be more settings relevant:

In www.conf the value of request_terminate_timeout should be equal to max_execution_time. In the host configuration of nginx you might need to set fastcgi_read_timeout for php-files.
