Thanks for posting about this here in the Community!
We'd first recommend turning your device off, waiting a couple minutes and turning it on again.
If that doesn't do the trick, we'd suggest making sure that both Spotify and Google Clock are rocking the latest version available. You can also give it another try using a different WiFi connection.
On another note, we've gone ahead and removed your screenshot since it contained some personal details. If you see the same or a different error message after trying the steps above, you can share again a screenshot of what you see so we can take a closer look. Just make sure that there's no private or sensitive info displayed.
Let us know how it goes! We'll be right here if you need more help.
Have a lovely day :)
