We could not scan this website!

Error text of the first response:

net::ERR_CONNECTION_REFUSED

This can happen for multiple reasons:

  • The site could not be contacted (DNS or generic network issues)
  • The site uses insecure TLS (weak ciphers e.g.)
  • The site requires HTTP authentication

Take a look at the JSON output or the screenshot to determine a possible cause.
