Connection to MongoDb server hosted on CentOS is failing

Question

Mongo up and running on CentOs Machine

All IPs enabled, no authorization

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0

# security: none
# authorization: 'enabled

Port enabled

netstat -tulnp
(No info could be read for "-p": geteuid()=1001 but you should be root.)
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

Connection from the server itself using the IP works fine

mongo --host 10.X.X.16
MongoDB shell version v4.2.2
connecting to: mongodb://10.X.X.16:27017/?compressors=disabled&gssapiServiceName=mongodb
MongoDB server version: 4.2.2
Server has startup warnings:
2020-01-21T15:48:26.297-0800 I  CONTROL  [initandlisten]

Doing the same thing from a remote Windows Machine

mongo --host 10.X.X.16
MongoDB shell version v4.2.1
connecting to: mongodb://10.X.X.16:27017/?compressors=disabled&gssapiServiceName=mongodb

Thanks!

Problem fixed:

I had to disable the firewall for the mongo port

sudo firewall-cmd --zone=public --add-port=27017/tcp --permanent
sudo firewall-cmd --reload
