我目前正在使用Nginx反向代理设置TeamCity,但我的浏览器出错了.错误如下：

WebSocket connection to 'ws://ci.example.net/app/subscriptions?X-Atmosphere-tracking-id=0&X-Atmosphere-Framework=2.2.7-javascript&X-Atmosphere-Transport=websocket&X-Atmosphere-TrackMessageSize=true&X-atmo-protocol=true&browserLocationHost=http%3A%2F%2Fci.example.net' Failed: Error during WebSocket handshake: Unexpected response code: 501

我查看了Nginx错误日志和TeamCity错误日志,两者都显示为空.

我的Nginx配置如下：

server {
  listen 80;
  server_name ci.example.net;
  error_log /var/log/Nginx/error.log;
  proxy_intercept_errors on;
  error_page 401 403 404 /404.html;
  location / {
    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_set_header        X-Forwarded-Proto $scheme;
    proxy_pass          http://127.0.0.1:8111;
    proxy_read_timeout  90;
    proxy_redirect      http://127.0.0.1:8111 http://ci.fluxmc.net;
  }
}
#Websocket configuration
map $http_upgrade $connection_upgrade {
    default upgrade;
    ''   '';
}
server {
    listen 400;
    server_name ci.example.net;
    error_log /var/log/Nginx/error.log;
    proxy_intercept_errors on;
    location /tc {
        proxy_pass http://localhost:8111/tc;
        proxy_http_version 1.1;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $server_name:$server_port;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
    }
}

我真的不确定从哪里开始,我几乎完全遵循了documentation for TeamCity.如果您能提供任何帮助,我将不胜感激！
