Getting this error when trying to send new messages.
Tried the solution below and created new API key and updated Airbop with this new API key but it is still not working.

What am I missing?

    If you've confirmed that GCM is enabled in your Google Console project, you've set it as a Browser Key with nothing entered in the "Allowed Referrers (web sites), and have also tried regenerating your existing key, all of which did not work, then I'd suggest creating a new key using the instructions in the following article:

    That article describes how to create a new key in the Firebase Console (instead of the Google Console).
