@zhouxuemeng1988 Sorry for the delayed response. This issue happens when the network connectivity is poor/lost. You can grab this exception by looking into the callback that you attach to the connect method. The callback will be invoked with |

@kvasukib how I can attach listener for that callback? My stacktrace: com.amazonaws.AmazonClientException: Unable to execute HTTP request: Unable to resolve host "cognito-identity.eu-central-1.amazonaws.com": No address associated with hostname

@tajchert What version of the SDK are you using? Can you post the contents of your |

@kvasukib

|
@tajchert Thank you for the confirmation. Regardless, the SDK should be catching the exception and throwing it back to the application when the network call is made on the background thread. We will look into it. Can you post a sample code snippet right from where you create the credentials provider till the scan call is made? (Exclude the AWS configuration/sensitive information). |

@kvasukib I have already handled this throwable callback, but it still crash my app. try {
credentialsProvider = new CognitoCachingCredentialsProvider(
WXEnvironment.getApplication().getApplicationContext(),
cognito_pool_id,
Regions.fromName(region)
);
mqttManager = new AWSIotMqttManager(clientId, end_point);
mqttManager.connect(credentialsProvider, new AWSIotMqttClientStatusCallback() {
@Override
public void onStatusChanged(final AWSIotMqttClientStatus status,
final Throwable throwable) {
checkConnectionTime = System.currentTimeMillis();
statusCallBack = "Disconnected";
if (status == AWSIotMqttClientStatus.Connecting) {
Log.e(LOG_TAG, "Connecting...");
statusCallBack = "Connecting";
} else if (status == AWSIotMqttClientStatus.Connected) {
Log.e(LOG_TAG, "Connected");
checkConnectionTime = System.currentTimeMillis();
statusCallBack = "Connected";
} else if (status == AWSIotMqttClientStatus.Reconnecting) {
if (throwable != null) {
Log.e(LOG_TAG, "Connection error.", throwable);
}
statusCallBack = "Reconnecting";
Log.e(LOG_TAG, "Reconnecting");
} else if (status == AWSIotMqttClientStatus.ConnectionLost) {
if (throwable != null) {
Log.e(LOG_TAG, "Connection error.", throwable);
throwable.printStackTrace();
}
statusCallBack = "ConnectionLost";
Log.e(LOG_TAG, "Connection lost");
} else {
Log.e(LOG_TAG, "Disconnected");
}
if (stateLisenter != null) {
stateLisenter.onStateChange(statusCallBack);
}
}
});
} catch (AmazonClientException e) {
Log.e(LOG_TAG, "Connection AmazonClientException111.", e);
} catch (Exception e) {
Log.e(LOG_TAG, "Connection error1111.", e);

@zhouxuemeng1988 I have changed your code to look for the exception from the callback. try {
credentialsProvider = new CognitoCachingCredentialsProvider(
WXEnvironment.getApplication().getApplicationContext(),
cognito_pool_id,
Regions.fromName(region)
);
mqttManager = new AWSIotMqttManager(clientId, end_point);
mqttManager.connect(credentialsProvider, new AWSIotMqttClientStatusCallback() {
@Override
public void onStatusChanged(final AWSIotMqttClientStatus status,
final Throwable throwable) {
if (throwable != null) {
Log.d("", throwable.getMessage());
if (throwable instanceof AmazonClientException) {
} else if (throwable instanceof MqttException) {
} else if (throwable instanceof Exception) {
}
}
checkConnectionTime = System.currentTimeMillis();
statusCallBack = "Disconnected";
if (status == AWSIotMqttClientStatus.Connecting) {
Log.e(LOG_TAG, "Connecting...");
statusCallBack = "Connecting";
} else if (status == AWSIotMqttClientStatus.Connected) {
Log.e(LOG_TAG, "Connected");
checkConnectionTime = System.currentTimeMillis();
statusCallBack = "Connected";
} else if (status == AWSIotMqttClientStatus.Reconnecting) {
if (throwable != null) {
Log.e(LOG_TAG, "Connection error.", throwable);
}
statusCallBack = "Reconnecting";
Log.e(LOG_TAG, "Reconnecting");
} else if (status == AWSIotMqttClientStatus.ConnectionLost) {
if (throwable != null) {
Log.e(LOG_TAG, "Connection error.", throwable);
throwable.printStackTrace();
}
statusCallBack = "ConnectionLost";
Log.e(LOG_TAG, "Connection lost");
} else {
Log.e(LOG_TAG, "Disconnected");
}
if (stateLisenter != null) {
stateLisenter.onStateChange(statusCallBack);
}
}
});
} catch (AmazonClientException e) {
Log.e(LOG_TAG, "Connection AmazonClientException111.", e);
} catch (Exception e) {
Log.e(LOG_TAG, "Connection error1111.", e);

@kvasukib Thanks for your response, but I think doing this just prints the error log and doesn't solve the real crash. |
|
@zhouxuemeng1988 The issue you're getting is because of a slow/stale connection. You can set |
|
@kvasukib I did not set the relevant default values. I looked at the AWSlotMqttManager source and found one of the following default values: autoReconnect=true, needResubscribe=trueminReconnectRetryTime=4, maxReconnectRetryTime=64, maxAutoReconnectAttempts=10. The automatic reconnection has been set by default. I think that when the network is not good, the mqtt connection loss is acceptable, but should not crash my entire app.Thank you. |

@zhouxuemeng1988 Can we setup a call to discuss the issue further? You can email me at karthba at amazon dot com. |
|
@zhouxuemeng1988, we have not heard from you. Please reach out to @kvasukib via email so we can setup a call to diagnose the issue. |

I am facing the same issue. No Idea, why it's happening. The Internet connection seems to be working fine. |
|
Same issue. Whats the update. In my case I think its because of a hook that runs when the user gets confirmed so it causes a delay in the response |
|
A lot of my user are reporting this problem with S3 service with stable network connections (wifi) |
*I only initialized aws related services after requesting our own server, so the user's network should be good.
*aws lot mqtt
