WampServer HTTPS “refused to connect” (no replies)

From: [stackoverflow.com],

I created:

C:\wamp\bin\apache\apache2.4.9\ssl.crt\vhost.crt & C:\wamp\bin\apache\apache2.4.9\ssl.key\vhost.key

I edited:

C:\wamp\bin\apache\apache2.4.9\conf\extra\httpd-ssl to include:

<VirtualHost www.vhost.dev:443>

DocumentRoot "c:/wamp/www/vhostdev"
ServerName www.vhost.dev:443
ErrorLog "c:/wamp/logs/ssl_error.log"
TransferLog "c:/wamp/logs/ssl_error.log"

SSLEngine on

"%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

</VirtualHost>

The SSL Apache module is turned on.

www.vhost.dev is defined in the Windows host file correctly.

When I load [www.vhost.dev], I receive:

This site can’t be reached
www.vhost.dev refused to connect.
Try:
Reloading the page
Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED

There is nothing in C:\wamp\logs\apache_error.txt

There is nothing in Windows Event Viewer > Application.

Help appreciated.

Update: I created a 2nd .crt & .key for a 2nd vhost and the problem followed me when I tried to load the 2nd vhost over https. This problem has only existed since I reinstalled Windows from fresh.
