My mongoose database is refusing to connect locally

Question

I have been trying to connect my mongoose database locally to 27017 but it is refusing to connect.

I thought it might be an error in my code but all my other apps that I had previously built, that were fully functional and working before, have the same error when I try to run them.

I tried using the mongodb compass and running the mongod command in cmdm but nothing seems to work. What could be the reason for it?

I tried reinstalling mongodb but it didn't work as well.

This is the error output:

  \Desktop\rest-api\node_modules\mongoose\lib\connection.js:792
    err = new ServerSelectionError();
          ^

This is my code:

    import express from 'express';
    import { APP_PORT } from './config/index.js'; //We do not need to 
    const app = express();
    import mongoose from 'mongoose';
    
    
    mongoose.connect('mongodb://localhost:27017/rest-api', {useNewUrlParser: true, useUnifiedTopology: true}).then(()=>{
        console.log('Database connected');
    });
    
    
    app.listen(APP_PORT,()=>{console.log(`Server running on port ${APP_PORT}`)})
