I'm running Ubuntu 16.04 with Apache + PHP7.1-FPM, and have a script that consistently times out after 60 sec with a 504 Gateway Time-Out error. For the life of me, I can't find what config setting is limiting the script. I've made the following changes to my settings:


  • max_execution_time = 600
  • max_input_time = 300
  • memory_limit = 512M
  • default_socket_timeout = 600


  • request_terminate_timeout = 0


  • Timeout = 600

I've confirmed the PHP settings are working (via phpinfo()). What other config settings do I need to be looking for? I don't get anything of value in the apache2 or php-fpm error logs.
