testssl.sh Fatal error No IPv4/IPv6 address(es) available

I'm trying to test SSL/TLS implemented in my server. I'm using testssl.sh for this. Since I'm using Windows, I'm running it over Cygwin.

However, when I try it like so:
./testssl.sh https://www.google.com
I get the following error
Fatal error: No IPv4/IPv6 address(es) for "www.google.com" available

Same happened with the internal server that I was trying to test. I remember I had tested in few months back and it had worked but Im surprised why its not working now.
