[BUG]: Render streaming not working from Quest3

[meta-winster]

Package version

3.1.0-exp.8

Environment

* OS: Meta Horizon OS
* Unity version: 2022.3.27f1
* Graphics API: Vulkan
* Browser: Google Chrome Version 131.0.6778.109 (Official Build) (arm64)

Steps To Reproduce

1). Follow steps for setting up scene listed here: https://docs.unity3d.com/Packages/[email protected]/manual/create-scene.html

I just used the most simple 3D scene, without any VR cameras/ prefabs.

2). Build to Quest 3 device

3). Open webserver on laptop

4). Use adb logcat package if desired to monitor logs

Current Behavior

The appp builds successfully to the Quest3, and its runs. However, the sample receiver only ever receives a black/ empty screen from the Unity app running on the Quest3.

In the adb logcat, I keep getting the following error message:

I disabled all firewalls on the webserver machine. And the two devices are running on the same local network.

Expected Behavior

Expected to see the screen of the Unity app streaming from the Quest3 to the laptop the webserver is running on.

Anything else?

What I've tried:

• Disabling all firewalls
• Suggestions from this somewhat related thread: https://communityforums.atmeta.com/t5/Unity-Development/UnityWebRequest-Not-Working-on-Quest-3-quot-cannot-resolve/td-p/1093537, specifically editing the http allow downloads to always, and removing the force remove internet options for Oculus.
