Please provide your assistance in this matter.`

Answer 1

A 401 error means that the target URL is protected, and you need to provide username/password authentication.

you need to set the username and password in the client, or tune your server settings so that the service is not protected.

Check the TemperatureConverterStub class for methods that allow you to set username/password, or check the documentation of whichever tool you're using to create those classes for more information on this.
