Auth error in Local Nucleus service setting; Can not create local server

The problem I encountered was the error in the local nucleus service setting. The error made me unable to create a local server and unable to download Isaac Sim to the local server. Does someone know how I can fix it?

Here are the screenshots. I really need some help for this problem.


Plus, my log for auth is empty.

What OS are you running this on?

We support running on Ubuntu 20.04 and 22.04.

I checked my system and found the version Ubuntu 18.04, so the problem is my release version is not 20.04 or 22.04?

Yes, this is likely the issue keeping Nucleus from running properly.
