nginx – RoR 5.0.0 ActionCable wss WebSocket握手：意外的响

您好我正在尝试使用ror 5.0.0 beta(使用puma)进行简单的聊天
在生产模式上工作(在localhost中没有问题).

这是我的Nginx配置：

upstream websocket {
    server 127.0.0.1:28080;
}


server {

    listen 443;
    server_name mydomain;
    ssl_certificate ***/server.crt;
    ssl_certificate_key ***/server.key;
    ssl on;
    ssl_session_cache builtin:1000 shared:SSL:10m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers 
HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    ssl_prefer_server_ciphers on;
    access_log /var/log/nginx/jenkins.access.log;

    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://localhost:3000;
      proxy_read_timeout 90;

      proxy_redirect http://localhost:3000 https://mydomain;


    location /cable/{
        proxy_pass         http://websocket/;
        proxy_http_version 1.1;
        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection "upgrade";
        proxy_set_header   Host $http_host;
        break;
    }

   }

这是config / redis / cable.yml

生产：
????url：redis：// localhost：6379/1

发展：
????url：redis：// localhost：6379/2

测试：
????url：redis：// localhost：6379/3

和config / environments / production.rb

  # Action Cable endpoint configuration
  config.action_cable.url = 'wss://mydomain/cable'
  # config.action_cable.allowed_request_origins = [ 'http://example.com',/http://example.*/ ]

  # Force all access to the app over SSL,use Strict-Transport-Security,and use secure cookies.
  config.force_ssl = false

这是我收到的错误：

application – […].js：27’wss：// mydomain / cable’的WebSocket连接失败：WebSocket握手期间出错：意外的响应代码：301

有小费吗？ ：) 谢谢
