Can not connect Phone and PC under same Wifi | Mirror Networking for Unity | Page 1

Here's my NetworkManager script,
using Mirror;
using kcp2k;
using UnityEngine;
using System.Net;

public class Net_Manager : NetworkManager
{
    private KcpTransport kcpTransport;
    private IPAddress currentIP;
    private ushort currentPort;

    public override void Awake()
    {
        base.Awake();

        kcpTransport = GetComponent<KcpTransport>();
    }

    public void CreateRoom()
    {
        kcpTransport.Port = Room_Port();
        networkAddress = Room_IP();

        currentIP = StringToIPAddress(networkAddress);
        currentPort = kcpTransport.Port;

        StartHost();
    }

    public void JoinRoom()
    {
        networkAddress = Room_IP();
        kcpTransport.Port = Room_Port();

        StartClient();
    }

    public void LeaveRoom()
    {
        if (NetworkServer.active && NetworkClient.isConnected)
        {
            StopHost();
        }
        else
        {
            StopClient();
        }
    }

    public override void OnStartServer()
    {
        base.OnStartServer();

        UI_Manager.instance.SetIPAndPort(currentIP, currentPort);
    }

    private string Room_IP()
    {
        return UI_Manager.instance.GetRoomIP();
    }

    private ushort Room_Port()
    {
        string rawPort = UI_Manager.instance.GetRoomPort();

        if (ushort.TryParse(rawPort, out ushort port))
        {
            return port;
        }
        else
        {
            return 7777;
        }
    }

    private IPAddress StringToIPAddress(string str)
    {
        if (str.ToLower() == "localhost")
        {
            return IPAddress.Loopback;
        }

        if (IPAddress.TryParse(str, out IPAddress ipAddress))
        {
            return ipAddress;
        }
        else
        {
            return null;
        }
    }
}
