https://domain.com works, https://www.domain.com does not! Help!

Hi.

Can anyone point me in the right direction.

I have a domain that is hosted with iis7. The url rewrite module redirects all www.domain .com to domain.com and I have used the well documented rule to force the site to add https:// to the domain name.

Therefore I would expect all
http://www.domain.co.uk
http://domain.co.uk
https://www.domain.co.uk
https://domain.co.uk
www.domain.co.uk
domain.co.uk

should all go to https://domain.co.uk

But https://www.domain.co.uk gives a security error:

Your connection is not private
Attackers might be trying to steal your information from www.hunterbarrington.co.uk (for example, passwords, messages or credit cards). NET::ERR_CERT_COMMON_NAME_INVALID

My bindings attached as a screen shot.

The domain is on a dedicated ip address.
