CreateSession Node Fails Despite ini Changes

I am currently developing a networked game with the HTC Vive. The game involves having the VR scene run as a server, and then allowing clients to connect to the scene as spectators on computers. I am currently just trying to get the game working on LAN.

I do not know why, but when I opened the project again today, I am no longer getting these errors and it’s working correctly.
