nginx 服务器目录禁止索引？

我是在window下用的laragon集成环境用来学习开发laravel。启动nginx服务器可以打开localhost:8080，但是打不开WWW目录下面的网站，也就是XXX.dev，会提示服务器拒绝连接请求。切换成apache服务器不存在该问题
错误日志提示：
2017/08/08 09:40:24 [error] 9928#9048: *4 directory index of "D:/laragon/www/poi/" is forbidden, client: 127.0.0.1, server: localhost, request: "GET /poi/ HTTP/1.1", host: "localhost:8080"

nginx.conf的配置：

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;
