Incorrect connection header with MQTT over Websocket with AWS IoT

I have an issue with AWS IoT. I was using the same code for month. But suddenly it stopped working. I'm using Mqtt over Websocket with AWS IoT.

This is the simple bit of code I use.

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();
        }
   }
}

And I got this log :

AVERTISSEMENT: Connect request failure
MqttException (0) - java.io.IOException: WebSocket Response header: Incorrect connection header

At this stage I have no clue what is wrong. I was using this code for month. Nothing have changed and now it stopped working.

if somebody can help me sort this out, it would be awesome. Thanks.

I also have the same issue, Actually, if you are using the same access key and secret key in multiple regions you will face this issue. I have created different users for each region. it fixes the issue.

Might be due to org.eclipse.paho getting upgrade v1.1.1
