Hi

I encountered an error while calling a consumed soap webservice. Below is the error in the stack:

[1] The underlying connection was closed: An unexpected error occurred on a send.
   at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request)
   at ssTestWebservice.WRefPSA_PSQUERY_EXECUTE.WRefPSA_PSQUERY_EXECUTE.GetWebResponse(WebRequest request)

[2] The handshake failed due to an unexpected packet format.

Appreciate if anyone can give me advice. Thanks!
