Ubuntu 24.04 server: Stuck connecting after initial installation.

When I went to a web browser to localhost:8000 it showed a JSON error message in the browser.

After starting the installer again it worked.

Hard to tell what's happening here...I don't see the final plugin installed successfully message but there's a check next to the last step. I may bug you to learn more about your setup.
