Unable to connect to dynamoDB table - UnknownEndpoint: Inaccessible host: - amazon-dynamodb

Question

I'm new to dynamoDB. I have created a table and am trying to insert data into the table. It works well when I connect from my home internet. But when I try from my office network, I get the below error:
I suspect this is due to proxy issues. Can you please help me resolve this issue? Thank you.

Answer 1

Thank you for the pointers. I managed to solve the issue using below code snipped.
var proxy = require('proxy-agent');
AWS.config.update({
httpOptions: {
agent: proxy('http://{user_name}:{password}#<proxy>:<port>')
}
});
This is documented in amazon's aws-sdk configuration site: http://docs.aws.amazon.com/AWSJavaScriptSDK/guide/node-configuring.html
