I've registered just to add this:
I had the same "Cannot get real username" error, but in my case I was already using an FQDN and a trusted Letsencrypt cert.
The root cause for me was that the directory I chose already existed, and the solution was to remove that directory in NC and then re-run the "Setup/Test" again. Doing so, the test succeeded and the directory was created and populated with a single XML backup on my NC server.
