node.js - nodejs cant connect to mongodb using mongoose

Question

so all my applications were working just fine using mongoose, all of a sudden they all stopped. i cant connect to my database. however my deployed apps using mongoose databases work fine, but i cant access to any database using my local computer. here is a test server ive written. can someone help me whats happening.

const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser')

const app = express();

app.use(express.json())

const db = require('./keys').mongoURI;

mongoose.connect(db, { useNewUrlParser: true, useUnifiedTopology: true })
    .then(() => console.log('connected'))
    .catch(err => console.log(err))

const port = process.env.PORT || 5000;

app.listen(port, () => console.log('server running'))



module.exports = {
    mongoURI: 'mongodb+srv://ertemishakk:<password>@cluster0-xi4zx.mongodb.net/test?retryWrites=true&w=majority'
}

Terminal: server running MongoTimeoutError: Server selection timed out after 30000 ms at Timeout._onTimeout (/Users/ishakertem/Desktop/test/node_modules/mongodb/lib/core/sdam/server_selection.js:308:9) at listOnTimeout (internal/timers.js:536:17) at processTimers (internal/timers.js:480:7) { name: 'MongoTimeoutError', }

您可以遵循此代码我希望能解决您的问题

const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser')

const app = express();

app.use(express.json())


//Remove <password> and provide DB password
/**
 * Example: mongodb + srv: //ertemishakk:[e-mail]/test?retryWrites=true&w=majorit
 */
mongoose.connect('mongodb+srv://ertemishakk:<password>@cluster0-xi4zx.mongodb.net/test?retryWrites=true&w=majorit', {
        useNewUrlParser: true,
        useUnifiedTopology: true
    })
    .then(() => console.log('connected'))
    .catch(err => console.log(err))

const port = process.env.PORT || 5000;

app.listen(port, () => console.log('server running'))
