无法在 ubuntu AWS EC2 服务器上访问 nginx

Question

我正在尝试启动一个Python Web应用程序，做与往常相同的操作(并不是说我完全知道我在做什么(。通常，当我在服务器上运行nginx时，我会看到"错误的网关"，然后转到浏览器中的IP。无论出于何种原因，我现在都

超时了。编辑：我期待一个坏的网关，我什么也得不到

提前感谢，

我没有对默认配置文件做任何事情... 我的etc/nginx/sites-available/default看起来像这样

server {
listen 80;
server_name ec2-52-36-167-131.us-west-2.compute.amazonaws.com;
access_log  /var/log/nginx/test.log;
location / {
proxy_pass http://127.0.0.1:8000/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}

sudo service nginx status看起来像这样

当我在服务器上curl -I ec2-52-36-167-131.us-west-2.compute.amazonaws.com时，我得到了我期望的错误网关，但在本地计算机上我得到了超时。
