Socket.io not working on apache2 server with domain name

I am trying to implement socket.io in my react project, on development everything works perfectly fine, but on the production I am getting getting errors when trying to connect from the client side WebSocket error

server-side: server.js:

const server = createServer(app);const io = new Server(server, {  cors: {    origin: "*",  },  transports: ['websocket']});app.locals.io = io;const { addingOnlineUser, removeUserOnDisconnect } = require('./socket.io/listeners');io.on('connection', (socket) => {  console.log("New connection", socket.id);  // Listeners   // Handling Online Users  socket.on("addingOnlineUser", (data) => {    const onlineUsersData = addingOnlineUser(data);    io.emit('onlineUsersListener', JSON.stringify({      updatedOnlineUsers: onlineUsersData.onlineUsers,      updatedUser: onlineUsersData.updatedUser,      isUserOnline: true    }));  });  socket.on('disconnect', () => {    const onlineUsersData = removeUserOnDisconnect(socket.id)    io.emit('onlineUsersListener', JSON.stringify({      updatedOnlineUsers: onlineUsersData.onlineUsers,      updatedUser: onlineUsersData.updatedUser,      isUserOnline: false    }));  });});server.listen(3000, () => console.log('Server started on port 3000'));

client-side: socketio.js

export const socket = io("https://oldziej.pl", {  autoConnect: false,  transports: ['websocket']});

SocketIoContext.js:

useEffect(() => {    const connectToServer = () => {      setIsServerConnected(true);    }    const disconnectFromServer = () => {      setIsServerConnected(false);    }    socket.on('connect', connectToServer);    socket.on('disconnect', disconnectFromServer);    socket.on('connect_error', (err) => {      console.error('Socket connection error:', err);    });    return () => {      socket.off('connect', connectToServer);      socket.off('disconnect', disconnectFromServer);    };  }, []);

I am trying to change the apache2 configuration to accept the WebSocket traffic but with no success
