I can't log in to the nucleus server from Isaac Sim

Please help.
When I try to sign in to the Nucleus server from Isaac Sim, I get the following error and cannot sign in:

2021-04-08 05:21:06 [68,704ms] [Warning] [omni.client.plugin] Tick: authentication: Could not connect to discovery service at “ws://localhost:3333”, attempting fallback authentication

I changed the default nuclear server settings in _build / linux-x86_64 / release / experience / isaac-sim.json, but it didn’t make sense.
Can anyone please tell me why I can’t connect to the Nucleus server?
Thanks you.

Hi,

Could you try the new connection using the workstation IP XX.XX.XX.XX:3009 instead of using localhost:3009?

Try 127.0.0.1:3009 too. Can you also check if you can access the server on the browser at http://localhost:8080/login.

The warning is fine. It can we ignored.

Thank you for your reply.

I tried both [127.0.0.1:3009] and [localhost: 3009], but the problem was not resolved.
I can access the omniverse browser from http: // localhost: 8080 / login.

I wrote the IP address in the following place.
Is this correct?

_build/linux-x86_64/release/experiences/isaac-sim.json

    },
"isaac": {
    "nucleus": {
        "default": "omniverse://127.0.0.1:3009"
    }
}

Thanks you.

Hi

Did you try it?

I have the same problem using localhost and 127.0.0.1 (red). However, I am running all using docker containers. That is why only the real workstation IP (where I have all the containers) works (green)

You can use the command ip a to know the IP of the workstation
