Hi there,

Do you have a firewall like ufw or csf for example? If this is the case you need to make sure that you either allow the IP that you are connecting from via the firewall or you open the 27017 port for incoming connections.

To get your IP you can visit this site here:

Also to verify that the Mongo service is listening on you can run:

netstat -plant | grep 27017

Let me know how it goes.
