Ошибка подключения к MQTT серверу. В чем причина?

Question

[thatmaniscool]

Стараюсь подключиться к MQTT серверу (Cloud MQTT) с помощью библиотеки PahoMqtt.
Выдает следующие ошибки:
Reason code - 5, по документации REASON_CODE_NOT_AUTHORIZED.
Message code: нет прав на подключение.
Привожу код:

public static void main(String[] args) {
		String topic	= "Lesson_MQTT_server";
		String broker	= "tcp://m15.cloudmqtt.com:18594";
		char [] pass	= "qmaoaTfDebag".toCharArray(); // Fake pass
		String userId	= "oelmanhl";
		String content	= "Hello world!";
		int qos			= 0;
		
		
		try {
			MqttClient client = new MqttClient (broker, userId, new MemoryPersistence());
			MqttConnectOptions options = new MqttConnectOptions ();
			//options.setAutomaticReconnect(true);
			options.setCleanSession(true);
			options.setPassword(pass);			
			System.out.println ("Connecting..."); 
			
			client.connect(options); // Stop here, can't connect to MQTT server.
			System.out.println ("Conntected!");
			
			MqttMessage message = new MqttMessage ();
			message.clearPayload();
			message.setPayload(content.getBytes());
			message.setQos(qos);
			System.out.println ("Publishing message...");
			
			client.publish(topic, message);
			System.out.println ("Message published!");
			
			client.disconnect();		
			
		} catch (MqttException ex) {
			System.out.println ("Reason code: " + ex.getReasonCode());
			System.out.println ("Cause code: " + ex.getCause());
			System.out.println ("Message code: " + ex.getMessage());
		}

Решение: options.setName(userId).
