C# – WCF Exception: Could not find a base address that matches scheme http for the endpoint

I'm trying to host a WCF web service on a separate Website in IIS with https at 443 as the only binding.

The following configurations works well when I use it in a website which uses both the bindings (http(80) / https(443)). If I remove the http binding, it starts throwing the following error.

Could not find a base address that matches scheme http for the endpoint with binding BasicHttpBinding. Registered base address schemes are [https].

How do I make it work in an IIS website with https binding only?
