没有端点可以在https：//…上侦听该消息。 这通常是由错误的地址或SOAP操作引起的

Question

I'm using a 3rd party web service, i can view and run it no problem from the browser

I've added the Service References to visual studio and specified the namespage:

As it's a web app so i've copied the relevant bits from app.config to web.config

  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="MembersSoap">
          <security mode="Transport"> 
            <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> 
            <message clientCredentialType="Certificate" algorithmSuite="Default" />
         </security>
         </binding>
        <binding name="BookingsSoap">
          <security mode="Transport"> 
            <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> 
            <message clientCredentialType="Certificate" algorithmSuite="Default" />
         </security>
         </binding> 

      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="https://server/directory/Members.asmx" binding="basicHttpBinding" bindingConfiguration="MembersSoap" contract="MWSMembers.MembersSoap" name="MembersSoap" />
      <endpoint address="https://server/directory/Bookings.asmx" binding="basicHttpBinding" bindingConfiguration="BookingsSoap" contract="MWSBookings.BookingsSoap" name="BookingsSoap" />

   </client>
  </system.serviceModel>

Here's my method using the MWSBookings web service:

private string GetBookings()
{
    using (MWSBookings.BookingsSoapClient client = new MWSBookings.BookingsSoapClient())
    {
        try
        {

            var bookings = client.ListBookableActivitiesClassesCourses(GetMemberAuthHeader2(), 0123456, "5", false);
            return bookings.ToString();

        }
        catch (Exception ex)
        {
            return ex.Message.ToString();
        }
    }


}

When i build my solution and view the browser page i get the following error:

There was no endpoint listening at https://server/directory/Bookings.asmx that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

I have searched through all the other posts on Stack Overflow and none of the solutions have helped my situation. I've ensured the HTTP Activation Feature is installed, I've tried running the AppPool from appPoolIdentity to NetworkService and that didn't help. Also tried including maxRequestLength and maxAllowedContentLength in web.config and increasing limits but no difference.

I'd be grateful if anyone can offer any advise.

thanks Scott

The issue was with a proxy server, i've added the following lines before i call my webservice and the error message has now gone.

var proxy = new WebProxy("myproxy:8080", true);

proxy.Credentials = new NetworkCredential("username", "password");

WebRequest.DefaultWebProxy = proxy;
