Error when connection .NET WCF service on https

Question

I am trying to connect to a WCF service over https and i get the following error

An error occurred while making the HTTP request to https://mysite/App/Service/MyService.svc. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.

Please help me out of this issue. We need to move to prod by weekend.

Incidentally, I notice that the `` section has `strict="false"`. That is not good. Some time should be assigned to set [`Option Strict On`](https://stackoverflow.com/a/29985039/1115360) and correct any problems it highlights. — Andrew Morton, Sep 11 '19 at 15:51

By default, WCF configuration only supports HTTP protocol to expose the service, we need to set up the additional service endpoint in the System.ServiceModel section.
Please consider the below configuration.

<system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
    <protocolMapping>
      <add binding="basicHttpsBinding" scheme="https"/>
    </protocolMapping>
  </system.serviceModel>

Then we specify an https binding in IIS.

After publishing the service in IIS, we add the service reference on the client to generate the client proxy. It would auto-generate the https endpoint.

One thing must be noted is that we should trust the server certificate when calling the service with the HTTPS endpoint on the server-side. There are two ways to accomplished this.

Use the below code segments before instantiating the client proxy class.

ServicePointManager.ServerCertificateValidationCallback += delegate
            {
                return true;
            };

Install the server certificate on the client-side Trusted Root Certification Authorities(certificate store).

Feel free to let me know if the problem still exists.
