Security scanner doesn't work

I am trying to scan my OC instance with your security scanner.

All I get is that there is no instance or I used it too often. Both of them are not true.

Has anyone a clue why it doesn’t work? I am still on an OC instance from the 9.x branch and it is hosted at a web hosting company’s server.

Having the same issue here.

Might be a special case though, because my domain only has a AAAA (IPv6) record which may not be accessible from the security scanner’s server.

In the same position with the scanner, while I have previously been able to use successfully.

Is it working for others?

Interestingly when i stated the port number in the url to scanned it worked fine, albeit its the standard one for https.
