I would say, "Hey Google play the station, and it would state that it will play music on Pandora and then the message "Sorry, something went wrong. When you're ready, give it another try."
The music never starts playing unless I play Pandora from my phone and mirror it to my Google home WiFi.

Hi @Icuriel! Welcome to community.
I'd like to pass this along to our engineering team for further investigation.
I've enable a trace on your account to help us investigate. Could you replicate the issue and then let me know the time and date it happened.
Additionally, Google is really interested in what's happening when your Google Home device doesn't play as intended. When you request that content from your Google Home device, and if it fails to play correctly, file feedback with Google by saying "OK Google, file feedback.
This will send a diagnostic report to Google which will allow them to investigate as well.
Thanks for the help!
