I know this question had been asked before, but I'm seriously not finding an answer to this issue anywhere.
I deployed a Node.js app to Heroku successfully, but I cannot connect to my MongoDB Atlas cluster.
This is the error I get:
2020-04-07T10:39:20.723516+00:00 app[web.1]: Connection failed... MongooseError [MongooseServerSelectionError]: connection <monitor> to 54.72.180.237:27017 closed

This is how I connect to MongoDB:
mongoose
.connect(process.env.blog_db, {
useNewUrlParser: true,
useUnifiedTopology: true,
})
.then(() => console.log("Connected to MongoDB..."))
.catch((err) => console.error(`Connection failed...`, err));
And this is my environment variable (which I set exactly the same in Heroku).
The weird thing is, if I run nodemon index.js the app runs perfectly and it connects to the MongoDB Atlas cluster immediately, but the deployed heroku app doesnt seem to connect to the DB.
I am literally out of ideas and I'm plucking my hair here, so please if anyone had tackled this issue before, I need your help!
Thanks in advance!

I am working on a MERN project and Earlier my mongo server was working fine, but now that I have restarted my app it is giving me error i.e is

Enabling the IPV6 that MongoDB has disabled by default, by using the given command also I'm adding a reference for your understanding. mongod --ipv6
https://docs.mongodb.com/manual/core/security-mongodb-configuration/
I tried with the given piece of code and its working now,
mongoose.connect('mongodb://localhost:27017/db_name',
{
useNewUrlParser: true,
useFindAndModify: false,
useUnifiedTopology: true
}
);
https://www.section.io/engineering-education/nodejs-mongoosejs-mongodb/
mongoose.connect(
process.env.DB_CONFIG,
{
useNewUrlParser: true,
useUnifiedTopology: true,
useFindAndModify: false,
useCreateIndex: true,
}
)
.then((x) => {
console.log(
`Connected to MongoDB!`
);
})
.catch((err) => {
console.error("Error connecting to mongo", err);
});
This is the piece of code I have been working on and this works fine until this day.
I don't know why and got an error like this:

I tried adding my ip to network access in mongodb dashboard but didn't work
Sometimes this happens because of your own internet connection when you use mobile hotspot. In this case adding your IP may never work unfortunately because your IP may probably change every time you reconnect. When I had the same issue I restarted my connection and allowed all IPs in access network. And also make sure that your connection is stable.
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.

I have already update IP address to mongodb network access => IP Access list to 0.0.0.0/0
But the error has still occurred. I think this error is occurring due to the window firewall. But I have not any idea to resolve this.
My 'lessons/new' page loads fine on my localhost, but gives an error with heroku. The page will load, but it crashes immediately after in heroku. I added a console.log(foundClass) for getClassesById and the foundClass dislplayed correctly. Can someone please point me in the right direction?
class.js lines 27-33
module.exports.getClassesById = function(id, callback){
Class.findById(id)
.populate(
{path: 'lessons',
model: 'Lesson', $ne: null}
).exec(callback)
}
classes.js
router.get('/:id/lessons/new', function(req, res, next) {
Class.getClassesById([req.params.id], function(err, foundClass){
if (err){
console.log(err)
throw err
} else {
if (req.user && req.user.email == foundClass.instructor_email){
res.render('lessons/new', {class_id: req.params.id})
} else {
res.redirect('/');
}
}
})
});

'classes/show' is the page it is coming from
classes.js 104-114
router.get('/:id', function(req, res, next) {
Class.getClassesById([req.params.id], function(err, foundClass){
if (err){
console.log(err)
throw err
} else {
console.log('Found class.')
res.render('classes/show', {"class": foundClass})
}
});
});
It's giving that error because Mongo ID is supposed to be of a specific format. The error log says that it got "favicon.ico" as a param which violates the Mongo ID format.
You should validate the data ALWAYS before doing DB operations.
There's a package for string validation and sanitization: https://www.npmjs.com/package/validator
You can check if the param is in proper format by:
var validator = require('validator');
then in your route:
if (!validator.isMongoId(req.params.id)) {
// Param is not mongoId, throw error
}
