Works great for some hosts but not others?

Hey,

The plugin works great for some hosts, but is failing for a fairly large number, not sure if this is an issue at my side but I don’t think so –

[root@host scripts]# ./check_heartbleed.py -H www.google.com -p 443
OK: Server www.google.com TLSv1.0 is not vulnerable. TLSv1.1 is not vulnerable. TLSv1.2 is not vulnerable. SSLv3.0 is not vulnerable.

[root@host scripts]# ./check_heartbleed.py -H www.test.com -p 443
UNKNOWN: Server www.test.com closed connection without sending Server Hello.

Any thoughts?
