Isaac Cannot connect to Nucleus

Omniverse Isaac Sim
1

I have not seen this issue in the other posts, so posting a new one here.

I am running ISAAC on AWS docker container. I was able to configure the Isaac folder on the nucleus and it is working fine over web UI.

However when starting up isaac sim, i am still getting errors like - ```2022-04-29 22:39:50 [43,332ms] [Warning] [omni.client.plugin] Tick: authentication: Discovery(ws://localhost:3333): Credentials service not found!

Do you still see this issue with the 2022.1.0 release? With the new release Isaac Sim container does not include Nucleus

@ltorabi thank you for the update

@ltorabi Could you extend where to download Linux launcher in order to follow the instruction for advanced docker aws implementation? It only suggests to install launcher on windows? Could you extend, please?
also it is unclear wher to download windows launcher

_av

you can download the launcher from here: Omniverse Enterprise Licensing & Pricing | NVIDIA
you can download windows or linux launcher, depends on which system you are working

@ltorabi
It doesn’t seem to run on headless Linux easily, unfortunately

For Isaac Sim 2022.1.0, we recommend installing Nucleus from Launcher on a workstation. On a headless Linux setup, we recommend deploying the Omniverse Enterprise Nucleus docker stack.
