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:

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



# Where and how to store data. storage:   dbPath: /var/lib/mongo   journal:

    enabled: true

#  engine:

#  mmapv1:

#  wiredTiger:



# how the process runs processManagement:   fork: true  # fork and run in background   pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile   timeZoneInfo: /usr/share/zoneinfo



# network interfaces net:   port: 27017

#  bindIp: 172.31.90.193  # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.
