Google nest voice control "unexpected error"

[HelenaSwe]

Hi! I have been using my voice command "Hey Google, play Spotify" on my Google Nest for years. It has worked perfectly. Since prob a month back or so it won't work anymore. I get the "unexpected error"-reply ever time.

No problem however playin Spotify on the same device(s) if I connect in the Spotify app. Spotify is still connected in my Google Home app. 

Ideas/suggestions what to try?
