Im trying to connect to my MongoDB that is on my EC2 instance. I am able to connect to using the public dns with this statement:
mongoClient = new MongoClient("ec2-3-92-197-163.compute-1.amazonaws.com", 27021);
but if I tried to replace the "ec2-3-92...." with the private IP address, as such:
mongoClient = new MongoClient("172.31.90.193", 27021);
It gives me the error:
INFO: Exception in monitor thread while connecting to server 172.31.90.193:27021 com.mongodb.MongoSocketOpenException: Exception opening socket at com.mongodb.internal.connection.SocketStream.open(SocketStream.java:70) at com.mongodb.internal.connection.InternalStreamConnection.open(InternalStreamConnection.java:126) at com.mongodb.internal.connection.DefaultServerMonitor$ServerMonitorRunnable.run(DefaultServerMonitor.java:117) at java.base/java.lang.Thread.run(Thread.java:844) Caused by: java.net.SocketTimeoutException: connect timed out at java.base/java.net.PlainSocketImpl.socketConnect(Native Method) at java.base/java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:400) at java.base/java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:243) at java.base/java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:225) at java.base/java.net.SocksSocketImpl.connect(SocksSocketImpl.java:402) at java.base/java.net.Socket.connect(Socket.java:591) at com.mongodb.internal.connection.SocketStreamHelper.initialize(SocketStreamHelper.java:64) at com.mongodb.internal.connection.SocketStream.initializeSocket(SocketStream.java:79) at com.mongodb.internal.connection.SocketStream.open(SocketStream.java:65) ... 3 more

Is there something I'm missing that is preventing me from connecting to mongo using the private IP address?
I have set up the inbound rules as such:
and this is what my mongod.conf file looks like:
# mongod.conf
# for documentation of all options, see:
# http://docs.mongodb.org/manual/reference/configuration-options/
# where to write logging data. systemLog: destination: file logAppend: true path: /var/log/mongodb/mongod.log
