can't connect mongoDB atlas to heroku

i'm successfully connecting my mongodb to a cluster in the mongoATlas but when i try to connect to heroku i get this error :

> UnhandledPromiseRejectionWarning: MongooseServerSelectionError: connection <monitor> to 52.55.178.46:27017 closed

2020-03-29T22:14:32.041178+00:00 app[web.1]:     at Object.<anonymous> (/app/index.js:10:4)

and this is my code for connecting to mongoDb:

const uri = 
  "mongodb+srv://theosadxen:[email protected]/auth";
  mongoose
 .connect(uri, {
   useUnifiedTopology: true,
   useCreateIndex: true,
   useNewUrlParser: true
 })
 .then(() => console.log("Connected to mongodb..."));

I also faced a similar problem, and the first thing to do is test the new connection* (mongodb+srv://theosadxen:[email protected]/auth), still running from your computer. If the connection is established, then try:

Make sure your IP is whitelisted. The easiest solution is add the "All IPs" whitelist of 0.0.0.0/0

Then change the user's password to the password suggested by mongodb (Autogenerate Secure Password)

Modify this in your application and make a new commit for heroku, to restart everything. It worked for me, and I hope it helps you too.

*the end of URI is strange! Did you change something on this string?
