UnityWebRequest does not work on HoloLens

Hi, I want to download a txt-file from a Server. So here is my code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Networking;
5. public class DownloaderScript : MonoBehaviour {
6.    
7.      public void GetFile()
8.          {
9.              StartCoroutine(Check());
10.          }
11.          private IEnumerator Check()
12.          {
13.              UnityWebRequest www = UnityWebRequest.Get("http://examplesite.com/example.txt");
14.              yield return www.SendWebRequest();
15.              if (www.error != null)
16.              {
17.                  Debug.Log(www.error);
18.                
19.              }
20.              else
21.              {
22.                  Debug.Log(www.downloadHandler.text);
23.                
24.              }
25.          
26.          }
27.      }

It works perfectly on the Unity Editor, but not on the HoloLens Emulator and I dont get any error. "InternetClient" is activated in the PlayerSettings and I also tried to set www.chunkedTransfer = false. Did anyone had the same issue?

 

Edit: I updated Unity and it worked. So it was a Bug.

 

What version of unity were you running at the time of the bug and what version fixed it?
