I am trying access the Nucleus Server manually because I need to download a .usd file to create an instanceable asset of my robot. When I open the Isaac Sim User Interface and go to Content Browser → Omniverse-> localhost, I get “Failed to start url omniverse:://localhost”. I can use the robot in simulation if I start a standalone program, so the connection itself should be fine.
The main goal is not the connection to the nucleus server. The main goal is creating an instanceable asset. So giving me an answer that does not solve the nucleus server problem, but will help me create an instanceable asset will be just as good.
