Running a production server on Python disables stdoutput

I am using RedirectStandardError and RedirectStandardOutput of ProcessStartInfo to grap output and errors of python programs. This works correct when I run the test server using

app.run(host="0.0.0.0", port=8080)

. but when I use waitress or wsgiserver I got no output.

Any suggestions?

the C# code

static Process ExecuteCommand(string name, string file, string args)
        {
            var processInfo = new ProcessStartInfo(file, args);
            processInfo.CreateNoWindow = true;
            processInfo.UseShellExecute = false;
            processInfo.RedirectStandardError = true;
            processInfo.RedirectStandardOutput = true;

            var process = Process.Start(processInfo);

            process.OutputDataReceived += (object sender, DataReceivedEventArgs e) =>
                LogOutput(name, e.Data,false);

            process.BeginOutputReadLine();

            process.ErrorDataReceived += (object sender, DataReceivedEventArgs e) =>
                LogOutput(name, e.Data, true);

            process.BeginErrorReadLine();

            return process;
        }

        private static void LogOutput(string name, string data, bool isError)
        {
            Console.WriteLine(string.Format("at {0:d/M/yyyy H\\:m\\:s} {1}:{2}{3}",DateTime.Now, name, (isError ? "(error) " : ""), data));

        }
