Question

我已经创建了MQTT代理，并且已经配置了Web套接字。这是我的配置文件。（我不使用SSL）

#mqtt
listener 1883
protocol mqtt

#Websockets
listener 9001
protocol websockets

我正在运行我的MQTT代理（使用此命令$ mosquitto -c /path/to/mosquitto.conf），这是日志文件。

1569230648: mosquitto version 1.4.15 (build date Tue, 18 Jun 2019 11:42:22 -0300) starting
1569230648: Config loaded from /etc/mosquitto/mosquitto.conf.
1569230648: Opening ipv4 listen socket on port 1883.
1569230648: Opening ipv6 listen socket on port 1883.
1569230648: Opening websockets listen socket on port 9001.

在我的网站上，我有此代码。

<!-- Script to import MQTT -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/paho-mqtt/1.0.1/mqttws31.js" type="text/javascript">
</script>


<!-- Script to connect to MQTT broker and retrieve current values -->
<script>
var websocket =  "195.**.***.**"; 
    var port =  9001; 

    client = new Paho.MQTT.Client(websocket, port, "web_connection" + parseInt(Math.random() * 100, 10));    

    // set callback handlers
    client.onConnectionLost = onConnectionLost;
    client.onMessageArrived = onMessageArrived;


    var options = {
        onSuccess: onConnect,
        onFailure: doFail
    }

    // connect the client

    client.connect(options);
    .....

但是当我尝试连接我的网站时，Chrome出现此错误：

mqttws31.js:977 WebSocket connection to 'ws://195.**.***.**:9001/mqtt' failed: Error in connection establishment: net::ERR_CONNECTION_TIMED_OUT

我在路由器9001端口中打开。为什么客户端Web无法连接？

谢谢

Web客户端无法连接到MQTT Web套接字
