One signal create notification REST API fails sometimes - node.js

Question

I am using oneSignal for push notifications node.js. I am using the create notification api to send notification to the users, but i dont know why it works some times and sometimes gives timeout error
sendNotificationToUser(data) {
try {
var notificationData = {}
notificationData.app_id = oneSignalAppId
notificationData.headings = {
en: "Heading"
}
notificationData.contents = {
en: data.message
}
notificationData.include_player_ids = [data.deviceId]
var headers = {
"Content-Type": "application/json; charset=utf-8"
}
var options = {
host: "onesignal.com",
port: 443,
path: "/api/v1/notifications",
method: "POST",
headers: headers
}
var https = require("https")
var req = https.request(options, function (res) {
res.on("data", function (data1) {
console.log("Response:")
console.log(JSON.parse(data1))
})
})
req.on("error", function (e) {
console.log("ERROR:")
console.log(e)
})
req.write(JSON.stringify(notificationData))
req.end()
} catch (err) {
console.log("err in notification", err)
}
}
this api works 50% of times and 50% of times it responds with time out error, even all the inputs are correct
ERROR:
{
Error: connect ETIMEDOUT 104.18.225.52:443
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1107:14)
errno: 'ETIMEDOUT',
code: 'ETIMEDOUT',
syscall: 'connect',
address: '104.18.225.52',
port: 443
}

Answer 1

one simple solution is to directly hit the working ip, you can do this by including
host: 'onesignal.con' in headers and
host: '104.18.226.52' in options
this resolved my issue
to know more about how you can specify ip with host in https request
go here HTTPS request, specifying hostname and specific IP address
