ONE TIME PROJECT - Fix the DOCKER NGINX 504 Gateway Timeout

We have our docker setup and the images that we are using are nginx, php5.6-fpm, mariadb and phpmyadmin

Everything works well, I can provide the whole docker-compose.yml and other files for the ---------- 's just that, whenever the system loads from a PHP method POST, and being redirected to a page that has a missing file in it - It goes into a 504 timeout.

Basically, the nginx server is trying to find the missing files and that I believe is causing the 504 timeout.

Loading a page manually via link or url that has a missing file in it won't trigger the timeout ---------- just triggers after a PHP POST, whether if it's via AJAX or normal form POST.

Thank you!
