Why do I get this on my wryteasync() method : id = 11, status = waitingforactivation, method = "{null}", result = "{not yet computed}" ?

So I want to make a server that will send messages to some clients and the clients will execute a specific code for each command.
I have the following code for the client:

private async Task StartEchoClientAsync()
        {
            try
            {
                using (var tcpClient = new TcpClient("192.168.1.100", 9999))
                {

                    lbEchoClients.Items.Add("TcpClient: " + tcpClient.Client.LocalEndPoint + "created.");
                    var s = tcpClient.GetStream();

                    var data = new byte[1000];
                    var read = new byte[1000];

                    for (var i = 0; i < 120; i++)
                    {
                        await Task.Delay(1000);
                        try
                        {
                            data = Encoding.ASCII.GetBytes("Mesaj");
                            await s.WriteAsync(data, 0, data.Length);
                            data = Encoding.ASCII.GetBytes("");
                        }
                        catch (Exception e)
                        {
                            textBox1.Text += e.ToString();
                        }

                        try
                        {
                            await s.ReadAsync(read, 0, read.Length);
                            byte[] recBuf = new byte[read.Length];
                            Array.Copy(read, recBuf, read.Length);
                            string text = Encoding.ASCII.GetString(recBuf);
                            lbEchoClients.Items.Add("Received Text: " + text);
                            read = Encoding.ASCII.GetBytes("");
                        }
                        catch (Exception e)
                        {
                            textBox1.Text += e.ToString();
                        }
                        
                    }
                    tcpClient.Close();
                }
            }
            catch (Exception e)
            {
                    textBox1.Text += e.ToString();
            }
        }

And the next code is the server :

<pre>private async Task StartServerAsync()
        {
            try
            {
                var tcpListener = new TcpListener(new IPEndPoint(IPAddress.Any, 9999));
                tcpListener.Start();

                btnStartServer.Enabled = false;
                Console_textBox.Text += "Serverul este online !\r\n";

                while (true)
                {
                    var tcpClient = await tcpListener.AcceptTcpClientAsync();

                    _ = StartServerSideClient(tcpClient);
                }
            }
            catch(Exception e)
            {
                Console_textBox.Text += ">e.ToString() + "\r\n";
            }
        }
private async Task StartServerSideClient(TcpClient tcpClient)
        {
            Console_textBox.Text += "Client: " + tcpClient.Client.RemoteEndPoint.ToString() + " Connected\r\n";
            var s = tcpClient.GetStream();
            var buffer = new byte[1000];

            int bytesRead = 0;
            int bytesWrote = 0;

            while (true)
            {
                ok = false;
                await s.ReadAsync(buffer, 0, buffer.Length);

                byte[] recBuf = new byte[buffer.Length];
                Array.Copy(buffer, recBuf, buffer.Length);
                string text = Encoding.ASCII.GetString(recBuf);

                if (string.IsNullOrEmpty(text))
                    break;

                bytesRead += recBuf.Length;
                Console_textBox.Text +="Text : " + text + "  -  " + ok;
                switch (ok)
                {
                    case false:
                        byte[] data1 = Encoding.ASCII.GetBytes("command1");
                        var wrt1 = s.WriteAsync(data1, 0, data1.Length);
                        bytesWrote += data1.Length;
                        Console_textBox.Text += " command 1 \r\n";
                        break;
                    case true:
                        byte[] data2 = Encoding.ASCII.GetBytes("comand2");
                        var wrt2 = s.WriteAsync(data2, 0, data2.Length);
                        bytesWrote += data2.Length;
                        Console_textBox.Text += " command 2 \r\n";
                        break;
                }
            }
            
            s.Close();

        }

So at var wrt1 = s.WriteAsync(data1, 0, data1.Length); and at var wrt2 = s.WriteAsync(data2, 0, data2.Length); when the code runs after the first message is sent it won't send any more messages and both variables will run into a problem that doesen't kill the program Id = 11, Status = WaitingForActivation, Method = "{null}", Result = "{Not yet computed}".If I'm doing it completely wrong, I'm sorry, but I'm still learning.

What I have tried:

I tried to follow the code with debug and try to spot the problem but it wasn't anything obvious .
