Alexa Endloint Health Not Reachable

I’m new to home assistant, I’ve been using Zwave with Vera then moved into a new house and started using Home Assistant. Currently have the offcial Zwave plugin installed as well as Zwave JS UI. Also using the Alexa integration with a subscription to Nabu Casa. When I give a voice command to Alexa to turn off or on certain lights, it gives the bell confirmation as if it completed the request but nothing happens. When I look at the Alexa history, it shows the correct smart device request but says “Bedroom Light Brightness 0” and then “Endpoint Health not reachable”. But it’s not shutting off the light. Not sure what the issue is.
