nginx adding index.html to requests

[killer1337]

Hi everybody,
I am trying to set up a web app called opennote on my nginx server but
somehow it doesn't work. When I call the page the error log shows:

2014/10/16 13:12:39 [error] 21400#0: *11
"/var/www_opennote/Service/service.php/config/index.html" is not found (20:
Not a directory), client: 192.168.217.41, server: , request: "GET
/Service/service.php/config/ HTTP/1.1", host: "192.168.217.201:444",
referrer: "https://192.168.217.201:444/"

According to the developer of the app the problem appears to be that ngix is
adding the index.html to Service/service.php/config/

So the application is requesting Service/service.php/config/index.html when
it should be requesting Service/service.php/config/.

I already tried to add 

location / {
    autoindex off;
}

to my config but it didn't help.

My nginx config is:

server {
    listen 444 ssl;
    ssl_certificate     bla.crt;
    ssl_certificate_key bla.key;
    set $root_path "/var/www_opennote";
    root $root_path;
    set $socket
"unix:/var/run/fpm-00796029-695b-475a-a87c-f2b25af36486.sock";
    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass $socket;
        fastcgi_index index.php;
        include fastcgi_params;
    }
    access_log
/var/log/nginx/160232e2-896f-4d3b-9fec-1e08058c2bc2-access.log;
    error_log 
/var/log/nginx/160232e2-896f-4d3b-9fec-1e08058c2bc2-error.log;
    large_client_header_buffers 4 32k;
}

Thank you for any hint on how I can solve my issue!
