访问web service 报错Server was unable to process request

[SunShineGirl]

Imports API_Test.com.servigistics.dosd_uat

登陆按钮
Protected Sub btnok_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnok.Click
Dim ws As DOSDDispatchService = New DOSDDispatchService()
Dim login_result As LoginResult
Try
login_result = ws.CheckLogin(txt_user.Text.Trim, txt_pwd.Text.Trim)

Response.Write(ws.Url)
Catch ex As Exception
Response.Write(ws.Url)
Response.Write(ex.Message)
End Try
End Sub
DOSDDispatchService 、LoginResult是web service 的类
web service 的路径是https://dosd-uat.servigistics.com/dosddispatchservice/service.asmx

报错Server was unable to process request，请问肿么回事啊？

Server was unable to process request. ---> Invalid Login/Password

你的用户密码不对

和我的错误提示一模一样，难道真是账号和密码有问题？先谢谢了，再看看
