Пользовательская привязка с аутентификацией

Я получаю следующую ошибку, когда пытаюсь просмотреть wsdl (http://localhost:51230/OrderPlacementService.svc)

The 'CustomBinding'.'http://tempuri.org/' binding for the 'IOrderPlacementService'.'http://tempuri.org/' contract is configured with an authentication mode that requires transport level integrity and confidentiality. However the transport cannot provide integrity and confidentiality.

Что я уже пробовал:

Хотя у меня есть

httpTransport

определена ошибка говорит

authentication mode that requires transport level integrity

Я попробовал погуглить, но не смог найти решения. Пожалуйста, помогите решить эту проблему.
