body: <p>I have a web service that is called from my ssis.</p>
  
  <p>Used to work fine in test mode, when moved to live environment I get the error :</p>
  
  <p>[Web Service Task] Error: An error occurred with the following error message: "Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebserviceTaskException: Could not execute the Web method. The error is: Object reference not set to an instance of an object..    at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebMethodInvokerProxy.InvokeMethod(DTSWebMethodInfo methodInfo, String serviceName, Object connection)    at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTaskUtil.Invoke(DTSWebMethodInfo methodInfo, String serviceName, Object connection, VariableDispenser taskVariableDispenser)    at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTask.executeThread()". </p>
