Fatal error - non HTTP services

Hi there,

I run into an issue while using your tool. Basically what's happening is the discovery process found a SIP-related subdomain which naturally doesn't have port 80 open. Because of this, the tool exited with such error:

Traceback (most recent call last):

Any idea how to bypass such a situation while using your tool?

And thank you for your work building it.

Regards.
