I would suggest you start with the new debugging guide It’s a tutorial that should get you from setting up a server to streaming over a network:
Isaac Sim streaming may be a bit more complicated, and you’ll need to ask in the Isaac Sim forums about how to correctly configure it for VR. I will say that there might or might not be a CloudXR plugin inside of Isaac Sim, which significantly complicates things. A more reliable way to start is to use SteamVR with your Omniverse / Isaac Sim application, and use CloudXR with SteamVR.
