How can I make a Unity web request with the Oculus Go?

Hey there,

I tried to send a POST request with the Oculus Go. I used the Unity standard code (https://docs.unity3d.com/Manual/UnityWebRequest-SendingForm.html)

and it worked perfectly in Unity.

But when I loaded the program onto myOculus Go, it doesn't work. Do you have an idea how I may solve this problem?

It would be very nice if you could help me.
