Symfony - Nginx Configuration error : FastCGI sent in stderr "Primary script unknown" - php

Question

This is the first time I use nginx with Symfony, and I used the configuration that is on the Symfony document. I have the basic configuration of the latest version of nginx.
However, on my url: 127.0.0.1:83/app_dev.php/fr/admin/organisations
I get the error in my nginx project_error.log file :
2017/06/01 09:16:14 [error] 20204#20204:
*1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream,
client: 127.0.0.1, server: localhost,
request: "GET /app_dev.php/fr/admin/organisations/ HTTP/1.1",
upstream: "fastcgi://unix:/var/run/php/php7.0-fpm.sock:", host: "127.0.0.1:83",
referrer: "http://127.0.0.1:83/app_dev.php/fr/admin/organisations/1/edit"
My nginx server config (From Symfony documentation) :
server {
listen 83 default_server;
listen [::]:83 default_server;
server_name localhost;
root /var/www/SymfonySkeleton/web;
location / {
# try to serve file directly, fallback to app.php
try_files $uri /app.php$is_args$args;
}
# DEV
# This rule should only be placed on your development environment
# In production, don't include this and don't deploy app_dev.php or config.php
location ~ ^/(app_dev|config)\.php(/|$) {
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
# When you are using symlinks to link the document root to the
# current version of your application, you should pass the real
# application path instead of the path to the symlink to PHP
# FPM.
# Otherwise, PHP's OPcache may not properly detect changes to
# your PHP files (see https://github.com/zendtech/ZendOptimizerPlus/issues/126
# for more information).
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;
}
# PROD
location ~ ^/app\.php(/|$) {
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;

fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;
# Prevents URIs that include the front controller. This will 404:

# Remove the internal directive to allow URIs like this
internal;
}
# return 404 for all other php files not matching the front controller
# this prevents access to other php files you don't want to be accessible.
location ~ \.php$ {
return 404;
}
error_log /var/log/nginx/project_error.log;
access_log /var/log/nginx/project_access.log;
}
Any ideas ? I strongly assume that my configuration is not good
Thanks !

Answer 1

Remove the lines:
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
Though this may impact on the use of symlinks in your project. It will remove that error message though.

Answer 2

Please check the root path and the files under it .
