MqttPahoMessageDrivenChannelAdapter: Lost connection: Connection lost; retrying

Question

Please can someone why the Patho MQTT v3 Message Driven Adapter is continuously loosing connection when trying to subscribe to an HiveMQ 4.9 topic

Versions :

• org.springframework.integration:spring-integration-mqtt:5.5.2

• org.springframework.boot:spring-boot-starter:2.5.3

• org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.2.5

Here is the config:

@Bean
public MqttPahoClientFactory mqttClientFactory() {
    DefaultMqttPahoClientFactory factory = new DefaultMqttPahoClientFactory();
    MqttConnectOptions options = new MqttConnectOptions();
    options.setServerURIs(new String[] { "tcp://localhost:1883" });
    factory.setConnectionOptions(options);
    return factory;
}

@Bean
public MqttPahoMessageDrivenChannelAdapter inboundAdapter(MqttPahoClientFactory clientFactory) {
    return new MqttPahoMessageDrivenChannelAdapter("MyApp", clientFactory, "MyTopic");
}

Each time the ChannelAdapter issue this error :

2022-10-26 15:22:24.580  INFO 28190 --- [nio-8091-exec-1] o.s.i.endpoint.EventDrivenConsumer       : started org.springframework.integration.endpoint.EventDrivenConsumer@9490cb2

Please does somebody know the real impact of this situation and what I can do to stop these erros ?

Thanks
