Why does [https://scan.nextcloud.com](https://scan.nextcloud.com) can’t scan my nextcloud running on a [mooo.com](http://mooo.com) (dyndns) subdomain? It only says “Host not found” 😞 Some time ago this worked fine… ![image](https://help.nextcloud.com/uploads/default/original/3X/0/1/01eb8f30b9d7a6daafb60e2b7ba300b42359d845.png) ---

See here: [Security Scan says "Host not found" - #2 by Culogy](https://help.nextcloud.com/t/security-scan-says-host-not-found/228115/2) TL;DR: Try adding `/status.php` to the URL. ---
