Not able to access the sharepoint url that gives the XML content output from the C# console application.

When im trying to access the sharepointUrl its showing a 403 forbidden error in C#. I can able to access the sharepoint url using client context as below.

var strUserName = ConfigurationManager.AppSettings["UserName"].ToString();
var strPassword = ConfigurationManager.AppSettings["Password"].ToString(); //names[1];
string url = @"https://microsoft.sharepoint.com/SharepointSiteUrl";
var context = new ClientContext(url);
SecureString password = new SecureString();
foreach (var i in strPassword) password.AppendChar(i);
context.Credentials = new SharePointOnlineCredentials(strUserName, password);
Web web = context.Web;
context.Load(web);
context.ExecuteQuery();

When i replaces the url to https://microsoft.sharepoint.com/Sh...title('SharepointListName')/Items(2)/versions this is givivng 403 error.

when i'm accessing both the urls in browser https://microsoft.sharepoint.com/SharepointSiteUrl, this is navigating to microsoft credntials page.

whereas when i clear the cookies and access the below url https://microsoft.sharepoint.com/Sh...title('SharepointListName')/Items(2)/versions is throwing error as Access denied. You do not have permission to perform this action or access this resource.

This is giving XML output only after accesing to https://microsoft.sharepoint.com/SharepointSiteUrl and after giving the credentials to this then only im accessing the https://microsoft.sharepoint.com/Sh...title('SharepointListName')/Items(2)/versions

so how can i directly access the url to read the xml File.

I have also tried with httpweb

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);

System.Net.NetworkCredential credentialCache = new System.Net.NetworkCredential(strUserName, strPassword, strDomain);
webRequest.Credentials = credentialCache;
webRequest.Method = "GET";
webRequest.ContentType = "text/xml";
HttpWebResponse res = webRequest.GetResponse() as HttpWebResponse; //403 forbidden error

I have also tried with Httpclienthandler

var httpClientHandler = new HttpClientHandler()
{
Credentials = new NetworkCredential(strUserName, strPassword, strDomain),
};

var httpClient = new HttpClient(httpClientHandler);
httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/XML"));

var result = await httpClient.GetStringAsync(url);// 403
