I used the Proactive Events API to send push notifications to my Alexa, using my client id, client secret, and userId. This worked perfectly when I ran it locally. However, when I pushed my code to company servers, the push notifications would no longer send, and i would receive the error
Error https response: 403
requestId: 7ab5cce2-dd2b-8ecc-1097-855...
userId amzn1.ask.account.<id>
may not have subscribed to this event.
Is there a reason why the push notifications is not working on the server?
