python - flask+gunicorn+nginx部署失败原因？

尝试用gunicorn+nginx组合在AWS部署一个flask应用，不知道为啥老是不成功。。求助
nginx配置

/etc/nginx/sites-available/default

server {
        listen   80  ;

        server_name noorders.com ;

        root /home/The-Garden-of-Forking-Paths/  ;
        access_log  /home/The-Garden-of-Forking-Paths/log/nginx.log ;
        error_log  /home/The-Garden-of-Forking-Paths/log/nginx.err  ;

        location / {
                proxy_pass http://127.0.0.1:5000  ;
                proxy_redirect off  ;
                proxy_set_header Host $host  ;
                proxy_set_header X-Real-IP $remote_addr  ;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for  ;
            }
        location /static/ {
                alias /home/The-Garden-of-Forking-Paths/app/static/;
            }
        }

运行命令sudo service nginx start

gunicorn的配置文件为

/home/The-Garden-of-Forking-Paths/project.conf

workers = 4
bind = '127.0.0.1:5000'
proc_name = 'manage'
pidfile = '/tmp/app.pid' 

运行命令 gunicorn --config project.conf manage:app

域名服务商是Godaddy
DNS解析换成了DNSPod
AWS的弹性IP已经加入域名的A记录
折腾挺久了，还是没搞明白，求教是哪一步出了问题？万分感谢！
