Nginx cannot find files

This is my /etc/nginx/sites-enabled/lelisoft.conf

map $http_accept_language $lang {
  default en;
  ~cs cs;
}

server {
  listen 80;
  server_name lelisoft.com www.lelisoft.com;   
  root /var/www/lelisoft.com;
  index index.html;    
  location / {
    try_files $uri $uri/ /index-$lang.html /index.html;
  }
}

When I open any of the file, I get 404 error.

The nginx is serving other site well. I dont see a significant difference and problem in the setup. Nginx logs do not show an error either.
