Unable to log into the nucleus server for the first time

I am unable to log in to the nucleus. I included the the screenshots of how it looks and what i have done so far. kindly help.

Navigator UI opened in browser, but login failed.

No username/password were documented.

No "Sign Up"/Register button was visible.

.env file had no credential variables.

auth_cli tool was missing in the nucleus-auth container.

The supposed User Manager UI at http://<ip>:3010/app was not available (404).

Accessing http://<ip>:3010 showed Prometheus metrics, not a web interface.

Common Linux text editors like nano and vi were not available in the container.

🧪 Steps We Attempted:
✅ 1. Checked Docker Container Health

Ran sudo docker ps

Found most containers were restarting, including nucleus-navigator.

You later fixed that issue — Navigator UI became accessible. ✅

✅ 2. Attempted Default Credentials

Tried default: admin / admin

Did not work.

✅ 3. Looked for Credentials in Config Files

You checked your .env file → no credentials were present.

✅ 4. Tried auth_cli Tool

Entered nucleus-auth container:

sudo docker exec -it base_stack-nucleus-auth-1 bash

Looked in /omni/ and tried running ./auth_cli → it was not found.

Tried find / -name auth_cli → no such binary exists in the container.

✅ 5. Tried Web-Based User Manager

Accessed:

Got Prometheus metrics output (e.g., # HELP omni_server_core_thread_count)

Tried:

→ Got a 404 Not Found

Concluded: User Manager UI is not included/enabled in this deployment.

✅ 6. Considered Enabling Self-Registration

Since:

    No CLI

    No default credentials

    No user manager

@pakalehi i am just another user but am curious whether you had actually set up an account? another inquiry is where you are located; there are some regions that may be part of the region lock.

and just fyi - you don’t technically need nucleus to get started using the Omniverse apps. my understanding is that it’s mostly used for collaboration/livelink with other programs. so if it’s not a requirement for you, it should be okay to not have one set up.

As the previous poster mentioned, we no longer recommend nucleus at all. It is no longer being developed for individual workstation use. It is not required in anyway. Since you’re already having issues with it, I would just recommend you go ahead and uninstall it along with launcher as well, and install USD composer in the new way.

I wanted to import some assets from unreal engine in windows to Isaac sim in Linux. Can I do this without nucleus?

Yes you do not need Nucleus for any of that. Simply export your assets from Unreal as USD, and then open them as USD in Issac Sim. The OS does not matter.
