Here is my configuration files

    listen 443 ssl http2;
    server_name jcpro.dev;
    root "/home/vagrant/Projects/jcpro/public";

    index index.html index.htm index.php;

    location / {

    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log off;
    error_log  /var/log/nginx/jcpro.dev-error.log error;

    sendfile off;

    }

    location ~ /\.ht {
        deny all;
    }

    ssl_certificate     /etc/nginx/ssl/jcpro.dev.crt;
    ssl_certificate_key /etc/nginx/ssl/jcpro.dev.key;
}

I have tried listens to 127.0.0.01:9000 in both nginx and fpm www.conf files, it still not working.

Help me.... spending a day still can't fix it.
