Django Channels + Elastic Beanstalk

Question

我已经设置了一个应用程序负载平衡器，将/ws/请求重定向到端口5000，在那里我有达芙妮与4名工作人员（通过Supervisord重新加载）一起运行。然而，在Chrome控制台我得到的错误

WebSocket connection to 'wss://api.example.com/ws/' failed: WebSocket is closed before the connection is established.

尝试通过简单的JavaScript代码连接到我的WebSocket时（见Multichat相当接近的东西）。有任何想法吗？

Routing.py

websocket_routing = [ 
# Called when WebSockets connect 
route("websocket.connect", ws_connect), 

# Called when WebSockets get sent a data frame 
route("websocket.receive", ws_receive), 

# Called when WebSockets disconnect 
route("websocket.disconnect", ws_disconnect), 
] 

Settings.py

# Channel settings 
CHANNEL_LAYERS = { 
"default": { 
    "BACKEND": "asgi_redis.RedisChannelLayer", 
    "CONFIG": { 
     "hosts": ["redis://:xxxxx@xxxx-redis.xxxxx.1234.usxx.cache.amazonaws.com:6379/0"], 
    }, 
    "ROUTING": "Project.routing.channel_routing", 
}, 

}

，失败之前运行

// Correctly decide between ws:// and wss:// 
var ws_scheme = window.location.protocol == "https:" ? "wss" : "ws"; 
var ws_path = ws_scheme + '://' + window.location.host + "/ws/"; 
console.log("Connecting to " + ws_path); 
var socket = new ReconnectingWebSocket(ws_path); 

显然

JavaScript代码，存在这意味着连接达芙妮/工人日志中没有相关的输出可能没有被正确路由首先。

所有设置都正确 - '是一个权限问题。密切关注所有相关的AWS安全组（负载平衡器和属于目标组成员的实例）。
