Here is how I tried to make HTTP POST request

var webRequest = WebRequest.Create(url); //  https://example.com/login
webRequest.Method = "POST";
string postData = "client_id=testid&client_secret=testsecret";
byte[] byteArray = Encoding.UTF8.GetBytes (postData); //
// Get the request stream. //
Stream dataStream = webRequest.GetRequestStream (); //
// Write the data to the request stream. //
dataStream.Write (byteArray, 0, byteArray.Length); //
// Close the Stream object. //
dataStream.Close ();

webRequest.ContentType="application/x-www-form-urlencoded";
webRequest.Credentials = CredentialCache.DefaultCredentials;
webRequest.ContentLength = byteArray.Length;
...

 it always throws exception of "timeout " when call this line:

Stream dataStream = webRequest.GetRequestStream (); //

 Could anyone help me ? thanks.

If I recall correctly, it is possible that to make a WebRequest over an SSL connection, you will have to provide the clients certificate to the authenticating server. I do not have the reference page at this moment in time, but when I find them, I will post some info for you here.

Any news on this?

No sorry, we are investigating the possible solutions.

confirmed consistent exception during async post to HTTPS, vs. no problem to the same URL with the same data by HTTP.

System.Net.WebException: Error: ConnectFailure
  at System.Net.HttpWebRequest.EndGetRequestStream

any progress on a fix, or has anyone worked around it ?

I did read somewhere to set ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 for this error.. not sure if that's easy to override somewhere, or has it already been tried by someone and fails anyway ?

Hi:

Anyone check what jamesnorman post it first? about certificates?

Cheers,

Is there any update on this? Has anyone used the 'Post Method' successfully?
