[Mono-aspnet-list] Timeout exception using https GetRequestStream with paypal

[Andrus]

Code

HttpWebRequest objRequest = 
(HttpWebRequest)WebRequest.Create("https://api-3t.sandbox.paypal.com/nvp");
objRequest.Timeout =15000;
objRequest.Method = "POST";
objRequest.ContentLength = strPost.Length;
using (StreamWriter myWriter = new 
StreamWriter(objRequest.GetRequestStream()))
                myWriter.Write(strPost);

causes exception at GetRequestStream() :

System.Net.WebException: The request timed out
  at System.Net.HttpWebRequest.GetRequestStream () [0x0005f] in 
/usr/src/redhat/BUILD/mono-2.10.2/mcs/class/System/System.Net/HttpWebRequest.cs:752
  at NVPAPICaller.HttpCall (System.String NvpRequest) [0x00000] in <filename 
unknown>:0

Version information: Mono Runtime Version: 2.10.2 (tarball Mon Apr 18

How to fix this ? Are there issues using https ?
Same application accessing same url runs OK in .NET 3.5 and probably worked 
in earlier Mono 2.10
