Holograms 240 - Devices can't connect to server
I'm having trouble getting past Chapter 3 of Holograms 240.
To reduce user-error, I've resorted to running the Catchup-Chapters > 7-Finale files from the download package.
That project builds fine and runs properly within the Unity editor. It even connects to the local HoloToolkit Sharing Service as seen through the log.
However, after building and installing on the HoloLens devices, the Sharing Holograms app does not seem to connect to the Sharing Service server.
I've opened up the Windows Firewall to both local and public networks.
When I run Sharing Holograms on the HoloLenses, all I get a 4 robot heads that can be air-tapped, but then nothing. No connection to the server is logged.
The Unity computer and the 2 HoloLenses are all on the same WiFi network.
Any ideas what I could be doing wrong?
