request.GetResponse(); returns 407 (Proxy Authentication Required) even though correct credentials are supplied

I'm developing an application (in C#) which sends http requests. Everything works fine as long as there's no Proxy with authentication involved.

Here's my code:

request = (HttpWebRequest) WebRequest.Create(uri);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = length;
request.Proxy.Credentials = new NetworkCredential("hans", "maulwurf"); 
request.Credentials = new NetworkCredential("hans", "maulwurf");

using (var requestStream = request.GetRequestStream())
        {
            // now send it
            requestStream.Write(postBytes, 0, postBytes.Length);
            requestStream.Flush();
            requestStream.Close();
        }
WebResponse webResponse = request.GetResponse();

On the last line i always get 407. The credentials work in ie/ff.

Does anyone have suggestions what the problem might be? Any help is greatly appreciated!

I think you may need to also specify the proxy server. like this, for example,

IWebProxy proxy = new WebProxy("<Server IP>", <Server Port>);
proxy.Credentials = new NetworkCredential("hans", "maulwurf"); 
request.Proxy = proxy;
