Unauthorized Error while accessing Jira cloud rest api for Login in C#

[Kirankumar Ek]

I was trying to access JIRA login apis from the C# code and Unauthorized error is displayed. 

The code snippet is given below:

var mergedCredentials = string.Format("{0}:{1}", "<username>", "<password>");
var byteCredentials = Encoding.UTF8.GetBytes(mergedCredentials);
var encodedCredentials = Convert.ToBase64String(byteCredentials);

using (WebClient webClient = new WebClient())
{
webClient.Headers.Set("Authorization", "Basic " + encodedCredentials);

return webClient.DownloadString("https://<jira_url>/rest/auth/1/session");
}

Can you please help me to resolve the issue? The username and password are the ones which we use to login to our jira url. Even substituted the Profile name as the user name and the Jira token as the password. Still getting the Unauthorized error.
