Amazon web services 带有AWS IoT的Websocket上的MQTT连接头不正确

我对AWS物联网有意见。我一个月都在使用相同的代码。但它突然停止了工作。我在AWS IoT上使用Websocket上的Mqtt

这是我使用的简单代码

import com.amazonaws.services.iot.client.AWSIotException;
import com.amazonaws.services.iot.client.AWSIotMqttClient;

public class ThingMain {

    public static void main(String[] args) {

        String clientEndpoint = "endpoint.iot.us-west-2.amazonaws.com";
        String clientId = "testing";

        AWSIotMqttClient client = new AWSIotMqttClient(clientEndpoint, clientId, "accessKey", "secretKey");

        try {
            client.connect();
        } catch (AWSIotException e) {
            e.printStackTrace();
        }
   }
}

我得到了这个日志：

在这个阶段，我不知道哪里出了问题。我使用这个代码已经有一个月了。没有任何变化，现在它停止工作了

如果有人能帮我解决这个问题，那就太棒了。谢谢。

可能是由于org.eclipse.paho升级到v1.1.1，我也有同样的问题，实际上，如果您在多个地区使用相同的访问密钥和密钥，您将面临这个问题。我为每个地区创建了不同的用户。它解决了问题。

谢谢，这解决了我的问题。我将这一行添加到我的依赖项

“compile（组：'org.eclipse.paho'，名称：'org.eclipse.paho.client.mqttv3'，版本：'1.1.0'）{force=true}”
