Nginx + Yii app = js，css - net :: ERR_CONNECTION_REFUSED

Question

我有一个五月天的情况。我在新服务器上从apache移动到nginx，安装了nginx + php-fpm + mariadb。

现在除了MVC结构的错误之外，还有另一个错误 - Chrome控制台在jpg和css文件的连接上充满了red - net :: ERR_CONNECTION_REFUSED。

它能是什么？是资产Yii组件中的错误还是NGINX配置中的错误？这是我的配置。

server {
    listen 80; 
    server_name    example.ru; 
    root  /var/www/sites/example.ru; 

    set $yii_bootstrap "index.php";

    charset utf-8;

    location / {
        index  index.html $yii_bootstrap;
        auth_basic "Restricted Content";
        auth_basic_user_file /etc/nginx/.htpasswd;
        try_files $uri $uri/ /$yii_bootstrap?$args;
    }

    location ~ ^/(protected|framework|themes/w+/views) {
       deny  all;
    }

    location ~ .(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
       try_files $uri =404;
    }

    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }

    location ~ .php$ {
        fastcgi_pass php-fpm;
                fastcgi_split_path_info  ^(.+.php)(.*)$;
                set $fsn /$yii_bootstrap;
                if (-f $document_root$fastcgi_script_name){
                    set $fsn $fastcgi_script_name;
                }

                include fastcgi_params;
                fastcgi_param  SCRIPT_FILENAME  $document_root$fsn;


                fastcgi_param  PATH_INFO        $fastcgi_path_info;
                fastcgi_param  PATH_TRANSLATED  $document_root$fsn;
    }

    location ~ .css {
        add_header  Content-Type    text/css;
    }

    location ~ .js {
        add_header  Content-Type    application/x-javascript;
    }

}

.htaccess几乎是空白的
