Question

我无法找到解决此问题的方法。其他帖子谈论几分钟后断开连接。在握手期间第一次回复后，我的配置立即断开连接。超时似乎不起作用。错误日志告诉我什么。

为什么连接没有打开？

这是我的nginx配置：

 map $http_upgrade $connection_upgrade {
      default upgrade;
      ''      close;
 }

  upstream pythonserver {

        server 127.0.0.1:8888;

  }
  server{
         listen 80;
         server_name 209.97.139.107;

         location /chatsocket {

              proxy_pass http://pythonserver;
              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;
              proxy_buffers 8 32k;
              proxy_buffer_size 64k;
              proxy_read_timeout 86400s;
              proxy_send_timeout 86400s;
              keepalive_timeout 90;
              proxy_cache off;
              proxy_buffering off;
              proxy_http_version 1.1;
              proxy_set_header Upgrade $http_upgrade;
              proxy_set_header Connection "upgrade";
              include         uwsgi_params;
              uwsgi_pass unix:/home/apideveloper/api/app.sock;

        }
        location / {
              include         uwsgi_params;
              uwsgi_pass unix:/home/apideveloper/api/app.sock;

        }
}
