我正在使用 websocket-rails gem 来处理我的应用程序的消息传递服务。

Tech Stack : Rails 4.2.5, Ruby 2.3.0p0, Passengeras app-server (Also try with Puma), Thinas websocket server on port 3001, ngnixas web server and Websocket patch ofgem 'websocket-rails', github: 'moaa/websocket-rails', branch: 'sync_fixes'

当客户端点击 websocket 服务器时，它会主动触发服务器事件，client_connected我可以在websocket_rails_server.log打印的消息中看到，即

"++++++++++++++++++++++++++++++++++++++++++++++++++++++++++"
"+++++++++++ WebsocketRails Client CONNECTED ++++++++++++++"
"++++++++++++++++++++++++++++++++++++++++++++++++++++++++++"

但是，在客户端它突然以响应结束：

WebSocket connection to 'ws://beta.server.com/websocket' failed: Error during WebSocket handshake: Unexpected response code: 504

我已经尝试过有关 Github 问题以及 Stackoverflow 相关问题的所有解决方案，但还没有帮助。

我的 nginx 配置如下（如果需要的话）：

server {
    listen 80;
    server_name beta.server.com;

    root /var/www/server-rails/current/public;

    proxy_cache_bypass 1;
    proxy_no_cache 1;

    location /websocket {
      proxy_pass http://localhost:3001/websocket;
      proxy_http_version 1.1;
      proxy_set_header  X-Real-IP  $remote_addr;
      add_header Access-Control-Allow-Origin *;                                                                                
      proxy_set_header Upgrade websocket;
      proxy_set_header Connection upgrade;
      proxy_set_header Host $host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    passenger_enabled on;
    passenger_sticky_sessions on;
    passenger_app_env staging;
}
