An unexpected error occurred on a send. EOF or 0 bytes from the transport stream

I make a request to an https site with this code:

 webRequest = (HttpWebRequest)WebRequest.Create(new Uri(urlDestination));
            webRequest.Method = "POST";
            webRequest.ContentType = "application/x-www-form-urlencoded";
            webRequest.ContentLength = bytes.Length;

            Stream writer = webRequest.GetRequestStream();
            writer.Write(bytes, 0, bytes.Length);
            if (writer != null)
            {
                writer.Close();
            }

            response = new StreamReader(webRequest.GetResponse().GetResponseStream()).ReadToEnd();

and get this error:

System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Received an unexpected EOF or 0 bytes from the transport stream.

I after checking on the web about the error I found this solution and didn't worked:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

after taking to the supplier he said that he encountered this error

SSL_do_handshake() failed (SSL: error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher) while SSL handshaking

I know that the error is from my part but don't know how to make the request to skip the error.

The ssl3 statment did solve my issue, but I came across another suggestion that didn't apply to me but it does to you since you have a content length statement.

The suggestion is to remove that statement.

My working code follows:

//Create WebRequest
Uri JsonUri = new Uri(new Uri(JIRAInstanceUri), ServiceUri);
WebRequest RestWebRequest = WebRequest.Create(JsonUri);
RestWebRequest.Method = "GET";
RestWebRequest.ContentType = "application/json";
//Add proxy to WebRequest
ProxyServer.BypassArrayList.Add(JsonUri);
RestWebRequest.Proxy = ProxyServer;
//Setup authorization
string Base64Credentials = GetEncodedCredentials(UserName, Password);
RestWebRequest.Headers["Authorization"] = "Basic " + Base64Credentials;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
