Simple Unity Multiplayer Doesn't Work on Oculus Go

I'm building a program for our school wherein I hope to use Oculus Go clients connected to a PC host. I'm building it in the latest version of Unity (2018.2.6).

I'm starting with the most basic UNet connection scene since I'm a beginner at development for the Go (not a beginner with Unity). I have a OVRCameraRig, an empty with the NetworkManager, and some primitives for reference. I have an script on the empty that detects the presence of an XR device and either loads as host (if not XR) or client (if XR). I have verified that the conditional works in the script, but the Oculus will not connect to the PC as a client.

I've tested the scene with two PCs, and the client PC had no trouble connecting to the host. So I know the IP Address I'm using is correct and that there are no firewall issues.

My guess is that there is something unique to the Oculus Go that is preventing it from connecting as a client. Most posts I've read suggest it should "just work", so I'm left with no useful information as to why it isn't.

Has anybody encountered this problem before?
