HttpWebRequest with SSL

Hello I am having a bit of trouble trying to read data off of a https URL.
When I try to access the site with the code below I get a 401 Unauthorized
error code.

I have spoken with the server admin and he investigated and found out that I
am getting a 401.1 error which indicates that the login info I passed via
credentials is invalid.
I am not sure why this is because I am putting the correct login information
and I verify this by accessing the site via the browser and using the same
login info.
Is there a reason that the login info data is not being sent properly to the
server for authentication?
I have tried fixing this for a while and I did a bit of research on it and
cannot find any answers.

If anyone has some info or advice I would greatly appreciate it.

I put my test code below:
try

{

   HttpWebRequest webRequest = (HttpWebRequest)

   WebRequest.Create(new Uri("https://mysite.com/test.html"));

   NetworkCredential creds = new NetworkCredential("myuserid", "mypassword",
"mydomain");

   webRequest.Credentials = creds;

   webRequest.Method = "GET";

   // setup request stream

   HttpWebResponse webResp = (HttpWebResponse)webRequest.GetResponse();  //
401 unauthorized error exception

   Console.WriteLine(webResp.StatusCode);

   Console.WriteLine(webResp.Server);

   Stream answer = webResp.GetResponseStream();

   StreamReader _answer = new StreamReader(answer);

   Console.WriteLine(_answer.ReadToEnd());

}

catch (WebException wEx)

{

   Console.WriteLine("Debug Message: " + wEx.Message);

}
