Answer 1

You need to verify 2 things:-

• Check whether the site you are trying to access is really exists? URL is valid?
• The Credential you are using to authenticate must have permission to access the web which you are trying to access. Verify once by using to same credential via web browser.

Answer 2

in app.config file add the below line worked for me:

<system.net>
    <defaultProxy useDefaultCredentials ="true"></defaultProxy>
  </system.net
