Not connecting to remote server!

[Abdallah-Alwarawreh]

when i connect to localhost with unity it works fine, but when I upload it to my remote server it doesn't work it returns unable to connect to remote server, but when I try to connect with this site "http://amritb.github.io/socketio-client-tool/", it works just fine

app.ts:

import { SocketServer } from "./Classes/Server";
import { WebServer } from "./Web/WebServer";
import express, { Express, Request, Response } from 'express';
const PORT = process.env.PORT || 8080;
// const PORT = 8080;

const http = require('http');
const app: Express = express();
const server = http.createServer(app);

var GameServer = new SocketServer(server);
var AdminServer = new WebServer(app);

server.listen(PORT, () => {
    console.log(`Server listening on port ${PORT}`);
});

server.ts

constructor(server: http.Server) {
        this.io = new Server(server, {
            cors: {
                origin: "*"
            }
        });
        
        this.DatabaseHandler = new DatabaseHandler();
        this.Connections = [];
        this.Lobbies = [];

        this.io.use(async (socket: Socket, next: any) => {
            console.log("Hit!");
            .......
        });
}

unity version, platform or the device, maybe a log or c# snippet code to have an idea!

2021.3.19f1, unity editor on windows (android platform), the log just says unable to connect to remote server

socket = new SocketIOUnity(uri, new SocketIOOptions {
    Query = new Dictionary<string, string>
		{
			{"id", EncryptedId},
			{"username", EncryptedUsername},
			{"avatarURL", EncryptedAvatarURL},
		}
	,
	EIO = 4,
	Transport = SocketIOClient.Transport.TransportProtocol.WebSocket,
});

make sure the internet permission is enabled in the manifest (maybe its the cause)

<manifest xlmns:android...>
 ...
 <uses-permission android:name="android.permission.INTERNET" />
 <application ...> ... </application>
</manifest>

I'm testing in unity editor, it it doesn't work, but it is working on localhost, just the remote server that is not working

so maybe the remote server has kinda of security or not a valid version of socketio! and from the code you posted i don't see the import of socketio
const socket = require('socket.io');

like in the example:
https://github.com/itisnajim/SocketIOUnity/blob/main/Samples~/Server/index.js

[Abdallah-Alwarawreh]

nah, it is imported i just put the important part of the ts code, btw I'm using typescript

import { Connection } from "./Connection";
import { Server, Socket } from "socket.io";
import { Lobby } from "./Lobbies/Lobby";
import { DatabaseHandler } from "./MySqlConn";
import { Player } from "./DataTypes/Player";
import { MatchMakingConnection } from "./MatchMakingConnection";
const { Encrypt, Decrypt } = require('./Encryption/EncryptionManager');
const { v4: uuidv4, v4 } = require('uuid');
import * as http from "http"
