                      How to Connect Remotly MongoDB Server

1) Replace the BindIp string from localhost(127.0.0.1) To Publicly(0.0.0.0)

sudo vim /etc/mongod.conf

Old configuration:

  bindIp: 127.0.0.1
 
New configuration:

  bindIp: 0.0.0.0
 
2) Or if you want to add multiple public ips then use below format

  bindIp: 127.0.0.1;45.48.63.89;125.25.188.25
 
3) sudo service mongod restart

4) Make Mongo remote connection via command line tool

mongo --host 'mongodb://USER:PASSWORD@SERVER_IP:27017/DB_NAME?authSource=admin'

or you can try authSource by add  your db name too.

mongo --host 'mongodb://USER:PASSWORD@SERVER_IP:27017/DB_NAME?authSource=DB_NAME'
