Nucleus Workstation: Unauthenticated

Error occurred during installation of Nucleus Workstation: Unauthenticated.”

I was using it just fine for weeks but then today, first it could not find the server so I uninstall/reinstall it and now I get the error - Nucleus Workstation: Unauthenticated.
Any idea?

After account referesh/relogin, it installs but give me the original error I received beginning of the day.

The Nucleus service appears to be unresponsive.
Please check your Omniverse System Monitor and be sure the web services are enabled.
If they are enabled, restart the Omniverse System Monitor and try again.

Cannot connect to System Monitor Backend.

I am not sure what was the issue but it is solved after I reinstalled omniverse Isaac sim.
