PubNub Access Manager
As indicated in the comments, if you enable Access Manager with your key (which is now FREE for all types of accounts), you must provide access to the auth_key channels for reading and / or writing, which your server generates. See PubNub Access Manager for more information .
If you are not ready to implement this grant on the server side, disable the access manager on your key until you are ready to perform the required behavior on your server.
Once you have the basic functionality, we strongly recommend that you implement the Access Manager functions in your application so that you can control who has access to which channels and what type of access: read, write or manage. PubNub provides all the necessary checks when trying PubNub, but the PubNub client code.
