Basic Authentication not work

[maza70]

Can't use the http Basic-Authentication the statuscode is always System.Net.HttpStatusCode.Unauthorized. With the normal MessageHandler the code works. How to use the http Basic Authentification?

Thanks for your support!

Sample Code:

try
{
    var tlsConfig = new TLSConfig()
    {
        DangerousAcceptAnyServerCertificateValidator = true,
        Pins = new List<Pin>()
                {
                    new Pin()
                    {
                        Hostname = "*",
                        PublicKeys=new string[]{ }
                    }
                }

    };
    var handler = new NativeMessageHandler(false, tlsConfig);

    HttpClient client = new HttpClient(handler);

    var webdavUrl = new Uri("https://ubuntu/remote.php/dav/files/zpush");
    var passwordCache = new CredentialCache();
    passwordCache.Add(webdavUrl, "Basic", new NetworkCredential("xxx", "secret"));
    handler.Credentials = passwordCache;
    handler.UseDefaultCredentials = false;
    handler.PreAuthenticate = true;

    var request = new HttpRequestMessage(new HttpMethod("PROPFIND"), webdavUrl);
    var response = await client.SendAsync(request, HttpCompletionOption.ResponseContentRead).ConfigureAwait(false);
    var satuscode = response.StatusCode;

}
catch (Exception ex)
{
    Console.WriteLine(ex.ToString());
}
