Nginx возвращает «404 Not Found» при вызове модуля загрузки

Я установил Nginx и модуль загрузки после Путеводитель Мартина Фьордвальда, но всякий раз, когда я отправляю туда файл, я получаю общую страницу Nginx «404 Not Found». Файл не загружен.

Вот мой nginx.conf:

user              nginx nginx;
worker_processes  1;
worker_rlimit_nofile 20000;

pid               /var/run/nginx.pid;

events {
    worker_connections  2048;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    client_max_body_size 64M;
    sendfile        on;
    tcp_nopush      on;

    keepalive_timeout  3;

    gzip  on;
    gzip_comp_level 2;
    gzip_proxied any;
    gzip_types      text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;

    server_tokens off;

    # Allocate RAM for upload modules
    upload_progress uploads 5m;

    include /etc/nginx/conf.d/*;
}

Файлы в conf.d (включены в nginx.conf):

bitload.biz.conf

server {
    server_name  bitload.biz;
    return       301 http://www.bitload.biz$request_uri;

      #upload_pass_form_field "^fallback$|^login$|^usession$";

      upload_cleanup 400 404 499 500-505;

      track_uploads uploads 5s;
    }

    }

    # Redirect 404s to the homepage
    error_page 404 /index.php;

}

default.conf

server {
    listen 80 default;
    server_name _;
    root /var/www/html;
}

hostname.conf

server {
    server_name gigabyte.bitload.biz;
    root /var/www/html;
}

Вот код, который я использую для отправки загрузки файла (я пробовал его с общим примером, найденным на домашней странице модуля, но он все еще не работал):

Вот результат nginx -V:

Может ли кто-нибудь пролить свет на эту ситуацию? Это действительно поставило меня в тупик.

Заранее спасибо!
