Error Code "301014" while setting up HomePod

You need to have  Keychain enabled and be using Two-Factor Authentication, Bluetooth also needs to be on.

Try also restarting your iPhone (iOS device using to set up)

See: If you can't set up HomePod or HomePod mini - Apple Support

Hi, Rachael!

I came across another article with the same issue; apparently, this works:

1. Open Settings
2. Tap [your name] > Media & Purchases > Sign Out
3. Try setting it up again
