FastCGI sent in stderr primary script unknown while reading response header from upstream

I have in nginx.conf

upstream php-fpm7.0
{
    server unix:/run/php-fpm/php7.sock;
}

I have in conf.d/default.conf

location ~ \.php$ {
    include php-fpm;
}

I have in php-fpm

fastcgi_pass    php-fpm7.0;
include fastcgi_params;
fastcgi_param   SCRIPT_FILENAME         $document_root$fastcgi_script_name;
set             $path_info              $fastcgi_path_info;
fastcgi_param   PATH_INFO               $path_info;
# Additional variables
fastcgi_index   index.php;

But i get error 404. When i comment 

#location ~ \.php$ {
#    include php-fpm;
#}

files are available

Error even if

location ~ \.php$ {
    fastcgi_pass unix:/run/php-fpm/php7.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}

FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream

The same error if not using socket:

fastcgi_pass 127.0.0.1:9000;

Centos 7

Update 1.

After i used:

fastcgi_param SCRIPT_FILENAME $document_root/index.php;
fastcgi_param SCRIPT $fastcgi_script_name;
fastcgi_param FOLDER $document_root;
fastcgi_param FOLDER_SCRIPT $document_root$fastcgi_script_name;

I got $_SERVER['SCRIPT'] /index.php and $_SERVER['FOLDER'] /home/www/m-a-x/www and $_SERVER['FOLDER_SCRIPT'] /home/www/m-a-x/www/index.php

When i back 

    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

all works. Mystery.

You can always check nginx variables by adding them to return statement, for example:

location / {
    return 200 $document_root$fastcgi_script_name;
}

  1. Open the URL, a file will be downloaded, file will contain variables returned by nginx. For example /srv/www/index.php

  2. Check that nginx/php-fpm user group has access to the file:

    sudo -u www stat /srv/www/index.php

  3. Set permissions to read and execute the files for the www user group all along the path.

    chmod g+x /srv

    chmod g+x /srv/www

    chmod g+x /srv/www/index.php
