Security Scan says "Host not found"

Ok, I got it to work (and I still got my A+ rating :slightly_smiling_face:): I entered the following URL in the security scanner’s input prompt:
https://cloud.mydomain.ch/status.php

Instead of only (as I did in the past years):
cloud.mydomain.ch

Interestingly, the security scanner then displays:
https://cloud.mydomain.ch/status.php/nextcloud

Entering https://cloud.mydomain.ch/ alone doesn’t work either.

Does anyone know what’s going on?
