HI Umbraco version 7.3.0 Umbraco Courier 2.51.2

I have a setup where dev domain is http://dev-example.com and the production domain is https://example.com

I get this error:

System.Net.WebException: The request failed with HTTP status 403: Forbidden.
   at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)
   at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)

   at Umbraco.Courier.Core.Repository.Dispose()
   at Umbraco.Courier.Core.Tasks.PackagingTask.Dispose()
   at Umbraco.Courier.Core.BackgroundTaskRunner`1.ConsumeTaskInternal(T task)

I have this setup in the courier.config:

<repository name="https://example.com" alias="https://example.com" type="CourierWebserviceRepositoryProvider" visible="true">
            <url>https://example.com</url>;
            <user>0</user>
        </repository>
    <repository name="http://dev-example.com" alias="http://dev-example.com" type="CourierWebserviceRepositoryProvider" visible="true">
      <url>http://dev-example.com</url>;
      <user>0</user>

    </repository>

What is the correct way to set courier up for transfer from http to https
