I am getting error while connecting to mongoDB. I don’t know what went wrong. please help me to fix this.

note:-I have configure "Allow access from Anywhere"
Below is the error message.

MongooseServerSelectionError: Could not connect to any servers in your MongoDB Atlas cluster. One common reason is that you’re trying to access the database from an IP that isn’t whitelisted. Make sure your current IP address is on your Atlas cluster’s IP whitelist: https://www.mongodb.com/docs/atlas/security-whitelist/

Node.js v18.17.1
[nodemon] app crashed – waiting for file changes before starting…

Below is my code in 3 separate file index.js, db.js server.js

index.js

const express = require("express");
const cors = require("cors");

const app = express();
app.use(express.json());
app.use(cors());

app.get("/", (req, res) => {
  return res
    .status(200)
    .send({ message: "Welcome to ecommerce API-node", status: true });
});


module.exports = app;

server.js File

const app = require(".");
const { connectDb } = require("./config/db");

const PORT = 5454;
app.listen(PORT, async () => {
  await connectDb();
  console.log("eCommerce API listening on PORT: ", PORT);
});

db.js

const mongoose = require("mongoose");
const mongoDbUrl =
  "mongodb+srv://xxxxxxxxxx:*************@cluster0.------------.mongodb.net/?retryWrites=true&w=majority";

const connectDb = () => {
  return mongoose.connect(mongoDbUrl);
};

module.exports = { connectDb };

database is not connecting to application.

I didn’t try any different step.
