Read Events from EventHub in Unity3D and HoloLens - unity3d

Question

We are trying to show events from an Azure EventHub in our HoloLens application. When we run our project in Unity 3D, it works and paint the data from the events.
But when we deploy the same solution on the HoloLens, we don't receive events and also we don't receive any error.
Here is the code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Microsoft.MixedReality.Toolkit.UI;
using TMPro;
