I have setup moquette Mqtt Broker and connected with eclipse paho client(I will call this paho1). Subscribing to "in/*" topic.

I created another paho client(I will call this paho2), with different client Id of course, and published to broker with "in/device" topic.

At first, the packet was delivered successfully. However, when I disconnect paho2 and reconnect to the broker and send the same packet, it is not delivered to the paho1.

I wonder why this is happening. My settings for the paho client is "qos = 0" (tried 1 and 2 as well)

MqttConnectOptions connOpts = new MqttConnectOptions();
connOpts.setCleanSession(false);

I was looking at the log of broker and it comes as follow. When successful, my protocol version is printed to the log

When Successfully published
index.php/fa/21857/0/

When Publishing failed
index.php/fa/21858/0/

I've changed the subscription topic to "in/#" from "in/*". Still not getting the message from the broker ... I am only available to receive the first message. What have I setup wrong?

Can you share your code? The logs you shared are not really easy to read, unfortunately
