Despite using GCM as its push service, Chrome doesn't support payloads using the GCM method.

It supports payloads encrypted using the Web Push encryption standard. See also the blog post on the developers.google.com website.

You can either implement it yourself, or use a library such as web-push for Node.js or pywebpush for Python or web-push for PHP.
