My push notifications seemed to have stopped.
Under my recent notices, only my tests show up.
I can use my php class and api key to get my configured push notices, and they all show up:
Under recent events, when I send a test, it shows error “No FlightXML format type configured”
I am not sure where the next place to look is.
It looks like the FlightXMK API Key associated with your account when you first called RegisterAlertEndpoint was disabled a few months ago, thus invalidating your end-point registration.
You will need to call RegisterAlertEndpoint again using your current FlightXML API Key and re-supplying your endpoint URL in order to resume receiving alerts.
