Call HTTPS REST service from WCF

I need to call some REST services from a third parties server over HTTPS. My thinking was that I would create myself a nice little WCF library to handle these calls and deserialise the responses. I'm coming a tad unstuck though.

The services I am trying to call have a test service that simply responds OK.

I have created an OperationContract in my interface as shown below:

[OperationContract]
[WebGet(BodyStyle = WebMessageBodyStyle.Bare,
    ResponseFormat = WebMessageFormat.Xml,
    UriTemplate = "test")]
 string Test();

In my service code I have a public method below:

public string Test()
{
    ChannelFactory<IService1> factory = new ChannelFactory<IService1>("UMS");
    var proxy = factory.CreateChannel();
    var response = proxy.Test();
    ((IDisposable)proxy).Dispose();
    return (string)response;
}

My app.config looks like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.web>
    <compilation debug="true" />
  </system.web>
  <system.serviceModel>
    <client>
      <endpoint address="https://61.61.34.19/serv/ums/"
              binding="webHttpBinding"
              behaviorConfiguration="ums"
              contract="WCFTest.IService1"
              bindingConfiguration="webBinding"
              name="UMS" />
    </client>
    <services>
      <service name="WCFTest.Service1" behaviorConfiguration="WCFTest.Service1Behavior">
        <host>
          <baseAddresses>
            <add baseAddress = "http://localhost:8731/Design_Time_Addresses/WCFTest/Service1/" />
          </baseAddresses>
        </host>
        <endpoint address ="" binding="wsHttpBinding" contract="WCFTest.IService1">
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <endpointBehaviors>
        <behavior name="ums">
          <clientCredentials>
            <clientCertificate findValue="restapi.ext-ags.801" 
                               storeLocation="CurrentUser" 
                               x509FindType="FindBySubjectName"/>
          </clientCredentials>
          <webHttp/>
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="WCFTest.Service1Behavior">
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>       
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <webHttpBinding>
        <binding name="webBinding">
          <security mode="Transport">
            <transport clientCredentialType="Certificate" proxyCredentialType="None"/>
          </security>
        </binding>
      </webHttpBinding>
    </bindings>
  </system.serviceModel>
</configuration>

I try to invoke the test method but receive the error "Could not establish trust relationship for the SSL/TLS secure channel with authority '61.61.34.19'."

Can anyone see what I'm missing here?

Any help appreciated. Cheers.

Try changing the webHttpBinding security setting from "Transport" to "None".

Could not establish trust relationship for the SSL/TLS secure channel with authority '61.61.34.19'.

This typically means there's a problem with the server's SSL cert. Was it self-signed? If so, you have to establish trust for the cert, typically by trusting the issuing CA or installing the cert in the windows cert store.
