I've been doing a google tutorial on how to send web push notifications on Chrome using web-push node module.
The thing is, the tutorial also provides a companion server app that you are supposed to use in order to test sending push notifications from a server to the client.
But, in both the companion app and even when using web-push cli on my local machine, when trying to send a notification I am getting a "Unauthorized Registration" error. Can't find anything online about this error - what am I doing wrong/ missing?
$ web-push send-notification --endpoint=https://fcm.googleapis.com/fcm/send/<<endpoint-key>>

Any company with a website can send web push notifications after installing code (a web-based SDK from a web push service) on its website. No app is required. For users, clicking or tapping on a web push notification takes the visitor to a pre-set URL determined by the brand.
Have you used any HTTP server to test the code in that tutorial? Further, DNS should be localhost or https:// site. If you are running the HTTP server under some port, better to have 5 digit client side port. Here is linked my project browser push
