Login failed and not getting a serial number?

Greetings,

I installed the daemon and configured it on a raspberry 4, problem is that I get the following non-stop:

2023-11-04T01:30:31.067334+00:00 pi4sala openskyd-dump1090[402817]: [INFO] [NET] Connection lost

I do have a username and I populated the field with that.
Any idea on what I am doing wrong?

Thanks!
