Cannot pair Apple Music with Google Home

I've had Apple Music paired with Google Home until today. My Nest Mini speaker said it wasn't paired when I tried to play music. I unlinked Apple Music in the Google Home app to re-link the accounts, but when walking through the wizard, idmsa.apple.com come back with, "Your session has timed out. Sign in again." I'm signed in to my Apple account & my Google account. Apple music works fine on my phone & the Roku connected to my TV.
