404 Not found with a sub-directory installation on nginx - L. C. - 09-02-2016

Hello,

you might notice I asked this question on StackOverflow as well. I'am really in a hurry to get a response.

A website - let's call it fru.it - servers a CodeIgniter application under fru.it/blueberry trough nginx and PHP-FPM. The main site resides in /var/www/fru.it/ on the filesystem, while the app is under /var/www/fru.it_blueberry/blueberry/ (different root than the main site). In an attempt to tighten security while CodeIgniter was upgraded to 3.1.0, the app's file structure was changed as per the CodeIgniter User Manual to:

Code:
/var/www/fru.it_blueberry/

├── blueberry

│   ├── application

│   ├── docs

│   ├── public

│   │   ├── index.php

│   └── system

└── sock

On development machines the setup works fine with Apache2's default mod_rewrite rules shipped with CI. Accessing fru.it/blueberry/ on the production server, however, displays a CI 404 page.
I'm sure it's a misconfiguration but I can't find the right detail by myself and have been trying with different setups. What do I need to change?

Application Configuration
The index file is modified to point to absoulte paths of diretories that got moved out of the public root:

Code:
$system_path = '/var/www/radiostudent.si_klubskimaraton/klubskimaraton/system'

$application_folder = '/var/www/radiostudent.si_klubskimaraton/klubskimaraton/application';

This is from application/config/config.php:

Code:
$config['base_url'] = '';

$config['index_page'] = 'index.php';

$config['uri_protocol'] = 'AUTO';

$config['log_threshold'] = 4;

In application/config/routes.php, a default controller is set to display the homepage at the bare address:

Code:
$route['default_controller'] = "Welcome";

$route['404_override'] = '';
