Nginx does not display 404 pages; instead, an index file in the root serves

Question

My Nginx server does not display my 404 page. Instead, when you try to access a page or directory that does not exist, it just maintains my index (.php) in the root of my web folder (without the corresponding stylesheet).

Here is my own default file under / etc / nginx / sites -available:

server {
listen 80;
listen [::]:80 ipv6only=on;
listen 443 ssl;
listen [::]:443 ipv6only=on ssl;

add_header Strict-Transport-Security max-age=15768000;
ssl_certificate /etc/nginx/ssl/server.crt;
ssl_certificate_key /etc/nginx/ssl/server.key;
ssl_protocols TLSv1.1 TLSv1.2;
ssl_ciphers 'ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DES-CBC3-SHA:HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4';
ssl_prefer_server_ciphers on;

root /usr/share/nginx/html;
index index.html index.htm;

location / {
    index index.php;
}

if (!-e $request_filename) {
    rewrite ^.*$ /index.php last;
}

try_files $uri $uri/ =404;

error_page 403 404 405 /error/404.html;
error_page 500 501 502 503 504 /error/50x.html;

location ^~ /error/ {
    internal;
    root /usr/share/nginx/html;
}

location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
}
}

This, no doubt, is new to me and works too much, so there are other problems here (on this note, a hint about how - as soon as the rest is fixed - I can make HTTPS connections swell!). Help and constructive input appreciated, thanks!
