使用AWS IoT通過Websocket與MQTT錯誤連接標頭

Question

我有一個AWS IoT問題。我在月份使用相同的代碼。但突然它停止工作。我使用AWS IoT通過Websocket使用Mqtt。

這是我使用的簡單代碼。

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(); 
     } 
    } 
} 

而且我得到了這個日誌：

在這個階段，我不知道什麼是錯的。我在月份使用這段代碼。沒有任何改變，現在它停止工作。

如果有人能幫我解決這個問題，那就太棒了。謝謝。

可能是由於org.eclipse.paho得到升級V1.1.1
