title: Getting error while authenticating salesforce login
body: <p>I'm using soap api for salesforce login authentication in C# but getting below error.</p>
  
  <blockquote>
    <p>UNSUPPORTED_CLIENT: TLS 1.0 has been disabled in this organization.
    Please use TLS 1.1 or higher when connecting to Salesforce using
    https.</p>
