The stack trace indicates that the server refuses the connection when you try to connect to https://play.hubhopper.co/0e4cb6416bf107bd883ebbc48f633428.mp3.

I don't think it has to do with the notification. The custom action seems to work as it has triggered playback but the network connection is refused.
