Salesforce Adapter in Publish mode - URI Scheme

Hi,

We are working on a new integration with Salesforce which is to receive notifications from SF to Neuron and then process it.

I am using the salesforce adapter in publish mode for this but when I specify the outbound notification url as https it fails to start with this error - 

Event Info: Adapter Endpoint 'SalesforceNotificationsEndpoint' reporting information.

The Outbound Notification Service failed to start

Url: https://testapi.xxx/SalesforceNotifications

Exception: The provided URI scheme 'https' is invalid; expected 'http'.
Parameter name: context.ListenUriBaseAddress

Method: .ctor

Stack: at System.ServiceModel.Channels.TransportChannelListener..ctor(TransportBindingElement bindingElement, BindingContext context, MessageEncoderFactory defaultMessageEncoderFactory, HostNameComparisonMode hostNameComparisonMode)
at System.ServiceModel.Channels.HttpChannelListener..ctor(HttpTransportBindingElement bindingElement, BindingContext context)
at System.ServiceModel.Channels.HttpChannelListener`1..ctor(HttpTransportBindingElement bindingElement, BindingContext context)

We have been able to host regular service endpoints using https but this adapter is faulting.

Any pointers would be helpful.

We are on Neuron 3.5.4.1130

Thanks.
