Nginx PHP-FPM 5.6 PATH_INFO jest pusty

Używam nginx 1.14.0 i php-fpm5.6 na Ubuntu 18.04. Kiedy patrzę na moje zmienne PHP za pomocą info.php, zmienna PATH_INFO jest pusta. Zastanawiam się, co może być nie tak?

/etc/nginx/sites-enabled/mysite.conf

location ~ [^/]\.php(/|$) {

        fastcgi_pass php56; # upstream server named in/conf.d/default.conf

        include fastcgi_params;

        fastcgi_keep_conn on;

        fastcgi_connect_timeout 30;

        fastcgi_send_timeout 600;

        fastcgi_read_timeout 600;

        fastcgi_buffers 256 16k;

        fastcgi_max_temp_file_size 0;

        fastcgi_index index.php;        # regex to split $uri to $fastcgi_script_name and $fastcgi_path

        fastcgi_split_path_info ^(.+?\.php)(/.*)$;        # Bypass the fact that try_files resets $fastcgi_path_info

        # see: [url=http://trac.nginx.org/nginx/ticket/321]http://trac.nginx.org/nginx/ticket/321[/url]

        set $path_info $fastcgi_path_info;        # Check that the PHP script exists before passing it

        try_files $fastcgi_script_name =404;

}

fastcgi_param   REDIRECT_STATUS     200;

Wyjście zmiennych PHP

_SERVER["DOCUMENT_ROOT"]/var/www/vhosts/mysite/site

_SERVER["DOCUMENT_URI"]/server/info.php

_SERVER["PATH_INFO"]    no value

_SERVER["SCRIPT_FILENAME"]/var/www/vhosts/mysite/site/server/info.php

_SERVER["SCRIPT_NAME"]/server/info.php
