MongoDB remote connection - Getting connection refused error

Application System IP: 10.0.0.15

MongoDB Server IP : 10.0.0.215

Here are a few details :

I'm running a Python web application on different system and mongo db on different system. Both systems can ping each other.

• I have replaced socket ip to connect to mongo db from 127.0.0.1 to mongo db system ip.

• Given MongoDB ip in application to connect but when running application I'm getting connection refused error.

• Added MongoDB system private ip with localhost,127.0.0.1 to bind variable in /etc/mongod.conf bind_IP = 127.0.0.1, 10.0.0.215

• Both systems are running on same network

• Application working fine when running mongodb on localhost.
• Do I need to make any changes in MongoDB client file dist-packages/pymongo/mongo_client.py also ?
