Can't access WCF service after versioning service contracts

I'm having trouble figuring out an issue with a WCF service that came up after I applied the "v2" contract to it to extend functionality. Everything builds fine, but when I try to access the service in the browser, I am simply told that it cannot connect. When I try to add it as a service reference, I get a similar message about connection problems. However, when I remove the extended contract endpoint from the config file and leave the old "v1" version intact, it works fine.

Here is the "v1" contract:

namespace Company.Services.Ticketing.Retail.Contracts
{
    [ServiceContract(Name = "OutletReportingContract_v1", Namespace = "https://enterprise.company.ie/Services/Retail")]
    public interface IOutletReportingContract_v1
    {
        /* methods */
    }
}

      

        
        
        
      

    

And here is the "v2" contract:

namespace Company.Services.Ticketing.Retail.Contracts
{
    [ServiceContract(Name = "OutletReportingContract_v2", Namespace = "https://enterprise.company.ie/Services/Retail")]
    public interface IOutletReportingContract_v2 : IOutletReportingContract_v1
    {
        /* methods */
    }
}

      

        
        
        
      

    

Here are the endpoints in the Web.config:

  <service name="Company.Services.Ticketing.Retail.OutletService" behaviorConfiguration="Public">
    <endpoint address="1" binding="wsHttpBinding" bindingConfiguration="Standard" name="OutletReportingContract_v1" 
        contract="Company.Services.Ticketing.Retail.Contracts.IOutletReportingContract_v1" />
    <endpoint address="2" binding="wsHttpBinding" bindingConfiguration="Standard" name="OutletReportingContract_v2" 
        contract="Company.Services.Ticketing.Retail.Contracts.IOutletReportingContract_v2" />
    <endpoint address="mex" binding="mexHttpsBinding" name="IMetadataExchange" contract="IMetadataExchange" />
  </service>

      

        
        
        
      

    

And here is the error message that appears in the event viewer:

WebHost was unable to process the request. Sender info: System.ServiceModel.Activation.HostedHttpRequestAsyncResult / 28075619 Exception: System.Web.HttpException (0x80004005): There was no channel actively listening at ' https: //phil-pc.company.local/Services/Retail/OutletService /_vti_bin/ListData.svc/ $ metadata '.

I looked down a bit and would be grateful for any help :)
