Nginx错误网关，9066＃0：* 13上游过早关闭连接，同时从上游读取响应头，

Question

我试图通过在瓶子框架上运行的uwsgi设置nginx。我不断收到502错误的网关，并且nginx错误日志显示9066＃0：* 13从上游读取响应标头时，上游过早关闭了连接，

9066#0: *13 upstream prematurely closed connection while reading response header from upstream, client: "ip address", server: "mydomain", request: "GET / HTTP/1.1", upstream: "uwsgi://unix:/run/uwsgi/myapp.sock:", host: "mydomain"

uwsgi .ini文件

[uwsgi]
module = run:application

master = true
processes = 1

uid = jimmy
gid = nginx
socket = /run/uwsgi/myapp.sock
chown-socket = jimmy:nginx
chmod-socket = 660
vacuum = true

die-on-term = true

nginx配置

user  jimmy;
worker_processes  1;
#error_log  logs/error.log; #error_log  logs/error.log  notice;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    client_max_body_size 20M;
    keepalive_timeout  0;
    proxy_connect_timeout 300s;
    proxy_read_timeout 300s;
server {
    # for a public HTTP server:
    listen 80;
    server_name "mydomain";

    location / {
        include uwsgi_params;
        uwsgi_pass unix:/run/uwsgi/myapp.sock;
    }

在我的瓶子run.py文件中

application = bottle.default_app()

我花了很长时间进行谷歌搜索，但仍然无法使nginx工作。任何帮助将不胜感激。
