IdentityServer 2 - Could not find a base address that matches scheme http for the endpoint with binding CertificateWSTrustBinding

I try use sample WcfIdentity45 > WSTrust > Symmetric from Pluralsight course Identity and Access Control in WCF 4.5.

I use IdentityServer v2.5

From client I request for token via WSTrustChannelFactory.

   var binding = new UserNameWSTrustBinding(SecurityMode.TransportWithMessageCredential);

    var factory = new WSTrustChannelFactory(binding, IDPAddress);

    //set up credetials
    factory.Credentials.UserName.UserName = "xxx";
    factory.Credentials.UserName.Password = "xxx123";
    factory.TrustVersion = TrustVersion.WSTrust13;


    //create token request
    var rst = new RequestSecurityToken
    {
        RequestType = RequestTypes.Issue,
        KeyType = KeyTypes.Symmetric,
        AppliesTo = new EndpointReference(ServiceAddress.AbsoluteUri)
    };

    return factory.CreateChannel().Issue(rst);

When I call Issue method I get error:

{"The requested service, 'https://domain:9988/issue/wstrust/mixed/username' 
could not be activated. See the server's diagnostic trace logs for more information."}

WCF service is accessible.

So I allow trace for IdentityServer 2, in wcfTrace.svclog I found this:

Exception:

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

Stak Trace:

I am confure because I code I don’t use never CertificateWSTrustBinding only ws2007FederationHttpBinding.

What is wrong?

EDITED:

I think this is root of problem when I hit https://domain:9988/issue/wstrust/ I get generic WCF error:

Could not find a base address that matches scheme http for the endpoint with

binding CertificateWSTrustBinding. Registered base address schemes are [https].
