Socket.io android not connecting it is working fine with web clinet not working in android

Hello I try to connect android my socket.io to my nodejs server which is hosted using ngnix

this is my android code which i have used in my android app

private var mSocket: Socket? = null
val opts = IO.Options()
opts.forceNew = true
opts.reconnection = true
val aara = arrayOf("websocket")
opts.transports = aara

try {
    mSocket = IO.socket(socket_url, opts)
    mSocket?.connect()
    mSocket?.emit("connection", "Nickname");
    mSocket?.emit("user_connect", "Nickname");
    Log.e("mSocket: ", mSocket?.connected().toString())
    mSocket?.on("connection") {
      Log.e("onCreate4w: ", "${it::class.simpleName} ${it.size}")
      Log.e("mSocket: ", mSocket?.connected().toString())
    }
} catch (e: URISyntaxException) {
    Log.e("onCreate25: ", mSocket?.connected().toString())
}

and server code is which is written in Nodejs

const io = soketio(server, {
  cors: {
    origin: [
      process.env.TYPEFORM_ORIGIN,
      process.env.ADMINPANEL_ORIGIN,
      
      "http://localhost:4200",
       "*"
      ,
    ],
    methods: ["GET", "POST"],
    allowedHeaders: ["my-custom-header"],
    credentials: true,
  },
  multiplex: false,
});
io.on("connection", (soket) => {
    soket.on("user_connect", (userId) => {
      // console.log("USER1", user);
      user[userId] = soket.id;
      // console.log("USER2", user);
      console.log("User Connected", soket.id);
    });

and this is ngnix configuration which are enabled in server

 location \ {
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_http_version 1.1;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_pass http://localhost:5555;
    }

Please guide us where we doing wrong this setup is working fine with web pannel, not in android

At first mSocket?.connect() do not return connected socket and you not able to emit immediately. At second you need to subscribe on different socket states to handle errors

mSocket!!.on(io.socket.client.Socket.EVENT_CONNECT) {
        Log.d(TAG, "connected") // emit is possible
    }.on("connection") {
        Log.e("onCreate4w: ", "${it::class.simpleName} ${it.size}")
        Log.e("mSocket: ", mSocket?.connected().toString())
    }.on(io.socket.client.Socket.EVENT_CONNECT_ERROR) {
        it?.forEach { out ->
            Log.w("EVENT_CONNECT_ERROR", out.toString())
        }
    }.on(io.socket.client.Socket.EVENT_CONNECT_TIMEOUT) {
        it?.forEach { out ->
            Log.w("EVENT_CONNECT_TIMEOUT", out.toString())
        }
    }.on(io.socket.client.Socket.EVENT_RECONNECT_ERROR) {
        it?.forEach { out ->
            Log.w("EVENT_RECONNECT_ERROR", out.toString())
        }
    }.on(io.socket.client.Socket.EVENT_RECONNECT_FAILED) {
        it?.forEach { out ->
            Log.w("EVENT_RECONNECT_FAILED", out.toString())
        }
    }.on(io.socket.client.Socket.EVENT_CONNECTING) {
        it?.forEach { out ->
            Log.d("EVENT_CONNECTING", out.toString())
        }
    }
mSocket!!.connect()
