I am using Ubuntu 20.04.3 and a local Nucleus Server 2021 3.2.
It was working yesterday without a problem. Today I updated Isaac Sim to version 2.1 and it stopped working (I’m not sure if it’s related).
If I go to localhost:3080 I get the error “Cannot connect to System Monitor Backend”
I tried uninstalling and installing nucleus again but it did not help. Here are my logs from /.nvidia-omniverse/logs and /.nvidia-omniverse/logs/Nucleus:

I came across that thread before posting my message but the suggestions there did not help (I could not find any ports.toml file in my omniverse folder).
I am using Ubuntu, so Drive is not an option for now, since it is only compatible with Windows.
Let me know exactly what files other than the ones I already posted could help figure out what’s wrong and I’ll upload them.
Hello @jominga. I passed along your log files to the development team to get some feedback from them.
Meanwhile, I took peek at your log files and found 2 errors that stood out to me:
Failed to lstat the base path “/home/USERNAME/.local/share/ov/pkg/nucleus-workstation-2021.3.2” for component nucleus-workstation@2021.3.2 Error: ENOENT: no such file or directory, lstat ‘/home/USERNAME/.local/share/ov/pkg/nucleus-workstation-2021.3.2’
Here are a couple of things you can try that have worked for other users. Let me know if you have already tried them.
Do you have a default Browser (like Chrome) set on your computer? If not, set one up so that Nucleus has a way to access the internet, then try to log in again.
and I can’t click on the ‘add local nucleus service’ button. A little history with this one. Omniverse was up and running. I had noticed an option to update Nucleus the other day and did not notice the outage warning. The update started, but never completed and I lost access to my local service. I tried to uninstall and re-install the launcher which ran fine (it must have found aspects of my previous install as I did not have to re-install create/view/connectors/etc), but it did not restore Nucleus to a running state.
Is there any way I can forcibly re-install Nucleus (e.g. remove some files and re-run the launcher install)?
note: I ran the cleanup tool and re-installed and I get the same problem. In the launcher logs, I see:

Nucleus is working for me right now… Have not spent a lot of time testing, but I was able to create a new service, etc. My install basically fixed itself this morning and I am running again. Thanks!
