Web Service invoke connection failure - VB .net on Visual Studio 2019 - Immediate Start Only

Already created an WS thru Service Reference in VS 2019 - as [login to view URL] - and have the following declaration below:

1 Module Module1


3 Sub Main()

4 Dim Xml As String

5 Dim sAnswer As String

6 Dim WS = New [login to view URL]()


8 Xml = "..."


10 Try

11 [login to view URL] = "SCF"

12 [login to view URL] = "1234567"


14 sAnswer = [login to view URL]("MovBillingProc", Xml)


16 [login to view URL]("Server Answer", [login to view URL])


18 [login to view URL]()

19 Catch Ex As Exception

20 End Try

21 End Sub


23 End Module

And facing the error below when executing line 14:

Ex {"The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was '*'."} [login to view URL] {[login to view URL]}

Probably reason: not determined that is BASIC authentication. Need someone to correct code to invoke a Web Service with authentication.
