I installed Isaac Sim on Ubuntu 20.04 machine. When I start it in headless mode I can use the client to connect to it, but when I am trying to access it through the client or WebRTC from another PC, with Windows 11, I cannot. An empty dark screen starts and then disappears. I see the following window then:
Unable to initiate a connection to the server. Please validate the server address ia accurate, and that it is reachable from the network.
looks like you were able to get it resolved by ensuring the Nucleus server is running 🙌 just going to link to the other thread here for potential users facing this issue:
and hopefully the doc’s team can add that note in the doc somewhere
