Amazon Alexa all entities unresponsive

I have been using HA with Amazon Alexa for a few years now and haven’t had any issue. I do use the integration through Nabu Casa. Recently, however, I had to restart my server. Since doing so every single entity I have is coming up as ‘Device Unresponsive’ in Alexa. I can control them just fine in HA, and automation work as well. However, this is killing the Wife Approval Factor. Does anyone know how to ‘reset’ so Amazon will stop being silly?

Thank you!

No help here but having the same issue. MQTT is working but Alexa is not seeing the data. Have tried disabling and re-enabling Alexa’s Home Assistant but didn’t try deleting. This happened after the 2023.4.3 or 2023.4.4 update. These recent updates keep breaking things. Hope someone can help.
