QuestionC# TcpListener listen forever Pin
Goga Work11-Mar-22 18:42
MemberGoga Work11-Mar-22 18:42 
I am new to C# and .net core , I am building billing program to read data from PBX which send on defined TCP port.
It does work , I receive the data but randomly tcp port stop listening and when I check window resource monitor I can see under Network --> Listening Ports --> it doesn't show .
But window service is running, then after restart window service i can see port start listening again.
There is no conflict of ports that I am sure of.

My code logic is as below :

C#
using CDR.Models;
using Newtonsoft.Json;
using RestSharp;
using System;
using System.IO;
using System.Net;
using System.Net.Sockets;

namespace CDR.Helpers
{
    /// <summary>
    /// Active or Passive.
    /// </summary>
    public class CDRServer
    {
        public static void Listen()
        {
            Logger.Log("Starting 3cX Listener");

            TcpListener server = null;
            try
            {
                // Set the TcpListener on port 5015.
                Int32 port = 5015;

                // IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName());
                // if (!ipHostInfo.AddressList.Any(d => d.AddressFamily == AddressFamily.InterNetwork))
                //   return;
                //IPAddress ipAddress = ipHostInfo.AddressList.FirstOrDefault(d => d.AddressFamily == AddressFamily.InterNetwork);//IPAddress.Parse("127.0.0.1");//

                IPAddress ipAddress = IPAddress.Parse("127.0.0.1");

                // TcpListener server = new TcpListener(port);
                server = new TcpListener(ipAddress, port);

                // Start listening for client requests.
                server.Start();

                // Buffer for reading data
                Byte[] bytes = new Byte[1024]; //this can be received.  //INVESTIGATE

                //100KB

                String data = null;

                // Enter the listening loop.
                while (true)
                {
                    Console.WriteLine($"Waiting for a connection...  on {ipAddress.ToString()} and {port.ToString()}");
                    Logger.Log($"Waiting for a connection...  on {ipAddress.ToString()} and {port.ToString()}");
                    // Perform a blocking call to accept requests.
                    // You could also user server.AcceptSocket() here.
                    TcpClient client = server.AcceptTcpClient();
                    Console.WriteLine("Connected!");
                    Logger.Log("Connected!");

                    data = null;

                    // Get a stream object for reading and writing
                    NetworkStream stream = client.GetStream();
