FtpWebRequest Fehler beim Verbinden in Testumgebung

Question

Ich versuche, eine Verbindung zu einem FTP-Server und Timeout-Fehler zu bekommen, auf meinem Ende funktioniert es, aber in der Testumgebung bekomme ich Timeout-Fehler, ich habe die Firewall deaktiviert, ersetzt die URL mit die IP und es funktioniert immer noch nicht da

ich verwende diesen Code:

var remoteFTPPath = ftpServer.StartsWith("ftp://") ? ftpServer : string.Format("ftp://{0}", ftpServer); 
      var request = (FtpWebRequest)WebRequest.Create(remoteFTPPath); 
      var networkCredentials = new NetworkCredential(userName, password); 
      request.Method = WebRequestMethods.Ftp.ListDirectory; 
      request.Credentials = networkCredentials; 
      response = request.GetResponse(); 
      } 
      finally 
      { 
       response.Close(); 
       response.Dispose(); 

      } 

und ich bin immer einen Fehler für sowohl aktiven als auch passiven Modus
