Self Signed Certificate + Custom Domain

Hi,

I am developing a web project which I want to bind the local address to a custom domain.

I could do easily and also I could run my project on eigther https and http with localhost.

The custom domain is working properly on http but not on https!!

Here is applicationhost.config which I have changed:

<bindings>
<binding protocol="http" bindingInformation="*:26:localhost" />
<binding protocol="http" bindingInformation="*:80:img.mydoamin.com" />
<binding protocol="https" bindingInformation="*:443:img.mydomain.com" />
<binding protocol="https" bindingInformation="*:44300:localhost" />
</bindings>

What should I do with the single certicate available in the IIS console? Please help me!

Thanks!
