First start your mongodb instance
mongod --port <your-choice-of-port> --dbpath=/path-of-your-db
and then connect to it.

I am trying to connect to my atlas cluster but it gives me time out error. I tried connecting to local mongodb, it works and using standard connection string for the same cluster:
(mongo "mongodb://cluster0-shard-00-00-n1kmr.mongodb.net:27017,cluster0-shard-00-01-n1kmr.mongodb.net:27017,cluster0-shard-00-02-n1kmr.mongodb.net:27017/test?replicaSet=Cluster0-shard-0" --ssl --authenticationDatabase admin --username <username> --password <password>)
works too!
However, when I try to connect with DNS Seedlist Connection Format, it gives me a timeout error when I run
mongo "mongodb+srv://cluster0-n1kmr.mongodb.net/test" --username <username>
Error message:
DNSHostNotFound: Failed to look up service "":This operation returned because the timeout period expired.

Then in another terminal, I did node app.js, which hangs (and does not print anything). Then I does http://localhost:28017 in a browser, it seems to work:
However, how could I see the website?
Edit 2:
The normal process is
install mongo
brew services start mongodb in a terminal
mongo & (assume we use the default folder /data/db/)
npm start
see e.g., bin/www for the port number, then use localhost:the_port_number in a browser
Update 2020 Feb 24:
It would be wise to stay tuned with it. Here is the link for latest library instruction:
https://docs.mongodb.com/manual/administration/install-community/
You haven't started your monogo database. first install mongo install mongo as per your OS https://docs.mongodb.com/v3.0/tutorial/
then follow instructions mentioned on this site:
https://docs.mongodb.com/v3.0/tutorial/getting-started-with-the-mongo-shell/
cd .
mongod --dbpath "any directory path to start your database "
and then start your node server. It will work fine.
Hope this helps!!
First open another terminal an run command mongod to start your mongoDB
Then again start you node server npm start or if you have "nodemon" then using nodemon
I think now everything will be fine it will show
Mongoose connected to mongodb://localhost/your_database
I had the same issue but it worked fine after restarting the service
service mongod start

It depends if you are using docker directly on a Linux host or on a Mac.
In the latter case, you would need to make sure you have port forwarded 57017 in your VirtualBox connection settings, as I mention in "How to connect mysql workbench to running mysql inside docker?"
