There is a external web services.

I can invoke it from my winform application, but I cannot invoke it from my asp.net mvc web application.

Error message is like this :

System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at http://ihexds.nist.gov:9080/tf6/services/xdsrepositoryb that could accept the message. This is often caused by an incorrect address or SOAP action.

Is there anything to configure for my mvc web application to consume it?

Edit :

following is my code to invoke web services

WCF.Message msgInput, msgOutput;
msgInput = WCF.Message.CreateMessage(MESSAGE_VERSION, PROVIDEANDREGISTERDOCUMENTSETB_WSAACTION, request);
msgOutput = WCF.Message.CreateMessage(WCF.MessageVersion.Soap12WSAddressing10, "");
 
string endpointName = GetRepositoryEndPointName();
XDSRepository.XDSRepositoryClient client = new XDSRepository.XDSRepositoryClient(endpointName);
 
msgOutput = client.ProvideAndRegisterDocumentSet(msgInput);
