Service Worker Registration - DOMException: Registration failed - could not retrieve the public key

[Sony Mathew]

In one of my devices (Chrome 55) I'm getting this error while registering the service worker. 

DOMException: Registration failed - could not retrieve the public key

But when I test it in other devices having Chrome 55, it works just fine. Can anybody throw some light on the cause of this error or in general in what situation this error is thrown.?

Hi,

This error message seems to be thrown from Push API when it’s failed to retrieve an encryption key. I'm not sure how this happen and how you can fix this (CC: push-notifications-dev)
