net::ERR_CONNECTION_REFUSED when I send a push notification

HI all,

I am using digital ocean and Ubuntu 14.04 x64 in production and it is deployed in a docker container

I have been using raix/push to send push notifications in my meteor/cordova app. It has been working successfully till recently.

When I send a push notification it works correctly in development but when I send one in production I get a net::ERR_CONNECTION_REFUSED error in the console

I also get W/chromium(10080): []

on the node server side.

Any clue to what is the problem and how I can fix it will be greatly appreciated
