Oculus Go Network Issue on opening Socket

Hi,
I try to open a socket on my unity application but it fails.
The code can run on android device or unity player but not on oculus.

My code 
            IPAddress ipAddress = this.LocalIPAddress();

            IPEndPoint localEndPoint = new IPEndPoint(ipAddress, 11000);

            try
            {
Exception occured here => this.socketlistener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
Exception => Protocol option not supported, it's socket exception

Log && Version
02-03 16:22:07.393 31073 31088 I Unity   : Unity v2018.3.4f1, Oculus Utilities v1.32.0, OVRPlugin v1.32.0, SDK v1.1.19.0.
02-03 16:22:07.571 31073 31088 E Unity   : Unable to find libc
02-03 16:22:08.317 31073 31088 E Unity   : StartServer: Protocol option not supported

Many thanks for help

PS : function used from prevous code 
        private IPAddress LocalIPAddress()
        {
            if (!System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable())
            {
                return null;
            }

            IPHostEntry host = Dns.GetHostEntry(Dns.GetHostName());

            return host
                .AddressList
                .FirstOrDefault(ip => ip.AddressFamily == AddressFamily.InterNetwork);
        }

    It seams that you can not open Socket with this method on oculus.

    I replace Socket open opening by a TcpListernet and it works.

    Hi @davidverriere
    is there a chance you can share part of your code to study how the sockets work through the oculus go I am still struggling with a basic connection of the go to my pc...

    Hi,
    I used the sample of TcpListener from Microsoft dotnet documentation : 

    using System;
    using System.IO;
    using System.Net;
    using System.Net.Sockets;
    using System.Text;

    class MyTcpListener
    {
      public static void Main()
      { 
        TcpListener server=null;   
        try
        {
          // Set the TcpListener on port 13000.
          Int32 port = 13000;
          IPAddress localAddr = IPAddress.Parse("127.0.0.1");
          
          // TcpListener server = new TcpListener(port);
          server = new TcpListener(localAddr, port);

          // Start listening for client requests.
          server.Start();
             
          // Buffer for reading data
          Byte[] bytes = new Byte[256];
          String data = null;

          // Enter the listening loop.
          while(true) 
          {
            Console.Write("Waiting for a connection... ");
            
            // Perform a blocking call to accept requests.
            // You could also user server.AcceptSocket() here.
            TcpClient client = server.AcceptTcpClient();            
            Console.WriteLine("Connected!");

            data = null;

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

            int i;

            // Loop to receive all the data sent by the client.
            while((i = stream.Read(bytes, 0, bytes.Length))!=0) 
            {   
              // Translate data bytes to a ASCII string.
              data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
              Console.WriteLine("Received: {0}", data);
           
              // Process the data sent by the client.
              data = data.ToUpper();

              byte[] msg = System.Text.Encoding.ASCII.GetBytes(data);

              // Send back a response.
              stream.Write(msg, 0, msg.Length);
              Console.WriteLine("Sent: {0}", data);            
            }
             
            // Shutdown and end connection
            client.Close();
          }
        }
        catch(SocketException e)
        {
          Console.WriteLine("SocketException: {0}", e);
        }
        finally
        {
           // Stop listening for new clients.
           server.Stop();
        }

          
        Console.WriteLine("\nHit enter to continue...");
        Console.Read();
      }   
    }

      Hi! 🙂 is this TcpListener used in your Oculus? Does it connect with any other socket in the network (for instance if I run a Python socket on my MacBook)?
