proxy setting in adal-node package - node.js

Question

I am trying to generate token to authenticate to Azure AD in my node server using adal-node package().Its working on my local machines but when trying to run on virtual machines its giving below error:
{
Error: getaddrinfo EAI_AGAIN login.microsoftonline.com login.microsoftonline.com:443
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:57:26)
errno: 'EAI_AGAIN',
code: 'EAI_AGAIN',
syscall: 'getaddrinfo',
hostname: 'login.microsoftonline.com',
host: 'login.microsoftonline.com',
port: 443` }
sample code snippet
var authorityUrl = 'https://login.microsoftonline.com/53d652a4-6f71-416f-971f-*****'
var applicationId = '26915ab6-22fc-4017-8741-***************'; // Application Id of app registered under AAD.
var clientSecret = '2NZtB5mIX1xZaXZ_I6I~-*********'; // Secret generated for app. Read this environment variable.
var resource = 'https://**************.com'; // URI that identifies the resource for which the token is valid.
var context = new AuthenticationContext(authorityUrl);
context.acquireTokenWithClientCredentials(resource, applicationId, clientSecret, function(err, tokenResponse) {
if (err) {
console.log('well that didn\'t work: ' + err.stack);
console.log(err);
res.json(err.stack);
} else {
console.log(tokenResponse.accessToken);
}
Analysis:It looks like proxy issue but unable to figure out how to set proxy url using adal-node package.Kindly suggest the way forward.

If you want to use the proxy server in your application, please refer to the following code
const { AuthenticationContext, Logging } = require("adal-node");
const proxy = require("node-global-proxy").default;
proxy.setConfig({
http: "",
https: ""
});
proxy.start();
const context = new AuthenticationContext(
"https://login.microsoftonline.com/const { AuthenticationContext, Logging } = require("adal-node");
const proxy = require("node-global-proxy").default;
proxy.setConfig({
http: "http://149.28.43.184:8080",
});
proxy.start();
const context = new AuthenticationContext(
"https://login.microsoftonline.com/e4c9ab4e-bd27-40d5-8459-230ba2a757fb"
);
Logging.setLoggingOptions({
log: function (level, message, error) {
console.log(message);
if (error) {
console.log(error);
}
},
loggingWithPII: false,
level: Logging.LOGGING_LEVEL.VERBOSE,
});
var applicationId = ""; // Application Id of app registered under AAD.
var clientSecret = ""; // Secret generated for app. Read this environment variable.
var resource = "";
context.acquireTokenWithClientCredentials(
resource,
applicationId,
clientSecret,
function (err, tokenResponse) {
if (err) {
console.log("well that didn't work: " + err.stack);
} else {
console.log(tokenResponse);
}
}
);
proxy.stop()
