The protocol 'https' is not supported

Question

I'm working with a WCF Service hosted in IIS however when i try navigate to the endpoint i receive the error "The protocol 'https' is not supported". It's hosted in IIS 10 locally running Windows 10.

The service is using wsHttpBinding with TransportWithMessageCredential.

Is this error something to do with the SSL certificate or IIS?

I already have a valid localhost certificate in my Local Machine > Personal certificate store.

What I've tried so far

1. Set the httpsGetUrl attribute to the .svc endpoint.
2. Checked IIS setting and default protocols is set to "http" which means both http and https protocols are enabled.
3. Checked that the Application Pool is using .NET Framework 4.0
4. Restarted the application pool

I appreciate if someone can assist me.

Here is the current config:

Answer 1

This particular error was resolved by removing the httpsGetUrl attribute from the configuration:

httpsGetUrl="https://localhost/Zootest_3_0/ZooServices_3_0.svc

So the end result looks like this:

<serviceMetadata httpsGetEnabled="true"/>

Answer 2

If you want to enable the https protocol support, you should add the https endpoint which use transport transfer mode to the service. Then we should set up the https protocol site binding in the IIS site binding module.

I have made a demo, wish it is useful to you.
Server end.

   [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string GetData(int value);     
        }
    public class Service1 : IService1
    {

        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }
    }
