Using Rabbitmq broker for mqtt, showing mqtt queue but not the message. Code below

Question

I am trying to send MQTT messages using RabbitMQ as a broker. I wrote the code below and tried to run it. I am able to see the MQTT Queue in the RabbitMQ dashboard, but there is no message. There is no message received, only the queue is being shown in Rabbit :/ Any advice, please?

This is how it looks like:

and this

Code:

using System;
using System.Text;
using System.Net;
using uPLibrary.Networking.M2Mqtt;
using uPLibrary.Networking.M2Mqtt.Messages;
using System.Threading;

namespace MQTTcl
{
    class Program
    {
      public static void Main()
        {
           // create client instance
           MqttClient client = new MqttClient(IPAddress.Parse("127.0.0.1"));
            // register to message received 
            client.MqttMsgPublishReceived += client_MqttMsgPublishReceived;
            string clientId = Guid.NewGuid().ToString();
            client.Connect(clientId);
            // subscribe to the topic "/home/temperature" with QoS 1 
            client.Subscribe(new string[] { "Xhindi" }, new byte[] { MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE });

        string strValue = Convert.ToString("This is a test message by Xhino!!!");
        string strValue1 = Convert.ToString("This is a test message by Sandri!!!");
        string strValue2 = Convert.ToString("KNP!!!");
        string strValue3 = Convert.ToString("KONTH!!!");
        System.Threading.Timer timer = null;
        timer = new System.Threading.Timer((obj) =>
        {


            // publish a message on "/home/temperature" topic with QoS 1 
            client.Publish("Xhindi", Encoding.UTF8.GetBytes(strValue), MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE, false);
           // client.Publish("Xhindi", Encoding.UTF8.GetBytes(strValue1), MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE, false);
           // client.Publish("Xhindi", Encoding.UTF8.GetBytes(strValue2), MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE, false);
           // client.Publish("Xhindi", Encoding.UTF8.GetBytes(strValue3), MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE, false);
           // timer.Dispose();
        },
                    null, 15000, System.Threading.Timeout.Infinite);
        int milliseconds = 5000;
        Thread.Sleep(milliseconds);
        //LoadJson();
        //writeJson();
