TTS to Google Nest Mini Speaker stopped working

Text to speech on Google Nest Mini Speakers has been working fine. There was a power failure and I also updated my Home Assistant, but since then TTS has not been working. I can’t see any change in the configuration that has made TTS to stop working.

Had the same a while ago. I unplugged the Mini for a minute or two, then restarted HA. and after that it was fine again.
