The http header analyzer tells us, that there are missing headers, while there are no header responses at all. So basically there seems to be no regular http service responding.
below is one of multiple examples
## http://10.10.10.2:593
* HTTP service does not redirect to HTTPS
* `content-security-policy` header missing
* `x-content-type-options` header missing
* `referrer-policy` header missing
Yes, the headers are missing, true, but there seems to be no regular http service.
