Alexa announcements suddenly stopped working

[karthiktx]

All,

I have Home Assistant with Alexa Media Player (local) integration. I have been using the type:tts notification on Echo Dot devices for the last few months for various events raised by zwave devices. Since today morning the announcements on echo devices are failing. Alexa is complaining that "Sorry. I'm having trouble accessing announce skill right now". I have tried enabling debug logs. It seems my automation script is firing properly. But the Alexa Echo devices are not announcing the message correctly. The Alexa app shows things are pretty normal except that it is not able to access the alexa device in "Thermostat". Any pointers on how I can debug this issue?

thanks,
Karthik
