Nginx 1.6 not loading .css and .js?

Question

Nginx

Windows 10, OpenServer.
On Apache it worked like this:

<link href="{{ asset('css/site.css') }}" rel="stylesheet">

Changed to nginx 1.6 , worked for a couple of hours, and began to give an error :

Symfony \ Component \ HttpKernel \ Exception \ NotFoundHttpException
No message
// или
Status Code:500 Internal Server Error

When you try to go to the file through the URL. I checked in google dev, the file seems to be loaded, but there is nothing in it.
Openserver configs:

Tried to add:

location ~ \.css {
    add_header  Content-Type    text/css;
}
location ~ \.js {
    add_header  Content-Type    application/x-javascript;
}
    location / {
        try_files $uri $uri/ /index.php$is_args$args;
    }
location / {
        try_files $uri $uri/ /index.php?$query_string;
        include /etc/nginx/mime.types;
    }
....
// и еще кучу вариантов из гугла по запросу nginx css fail

It began to knock out 404 nginx.
Php code works.
What am I doing wrong?

began to give an error:
Symfony \ Component \ HttpKernel \ Exception \ NotFoundHttpException

And you think that Nginx is to blame for this?
And you, as in a joke, look for lost keys, where is it brighter, and not where you lost them?
