Hi Ken,

The Service name needs to be memberService, not MemberService.

And make sure that you can request the webservice from the webserver the site is running on.

Cheers,
Tim

Hi Tim,

that can work,but I find some issues.

When I create one data source and then create second ,it will fail unless iis reset

error message is

Service Not Available

Another issue is that  web service  over use https protocol will throw exception:

umbracoForms: System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

I try add below code at Application_Start event,but cant not work 

ServicePointManager.ServerCertificateValidationCallback += delegate ( object

sender ,
      System.Security.Cryptography.X509Certificates.X509Certificate
pCertificate ,
      System.Security.Cryptography.X509Certificates.X509Chain pChain ,
      System.Net.Security.SslPolicyErrors pSSLPolicyErrors )
      {
       return true;
      };

Thanks for quickly answer ^ ^
