WampServer

I am using WAMPSERVER (64 BITS & PHP 5.5) 2.5, and I need to set up HTTPS for my websites, so I have followed the instruction from the links below,

[developersdigest.blogspot.co.uk]

and have also tried this one,

[indiesphp.com]

In the DOS Command windows, I enter httpd -t . it displays Syntax is OK.

But it says Unable to connect on my firefox when I hit https://{{localhost}}/

Any idea what I missed?

if I remove the comment # off from

#Include conf/extra/httpd-ssl.conf

in httpd.conf, then the wamp became offline permanently. Any idea what can I do about it?
