Web Services error in Data Services 4.1

Hi experts,

I'm working with a Web Services in Data Services 4.1 SP2 and the datastore not to validate the Web Services URL and gives the following error:

I tried the same Web Services on a server Data Services 4.2 SP5 and the error does not occur and there are also two versions of Web Services (SOAP and REST) while in version 4.1 there is only one version:

I hope you can help me please.

Many thanks.

Kind regards

Victor
