Linking Google Home with HA Linked Service/Skill (Android and iOS) FAILS every time

Good day!
I have a fresh install on RasPi and signed up for the cloud service. I have everything working locally but I can NOT get the Google Add on “Skill” to work:

Go to GOOGLE HOME → Setup Device → Works with Google → search: home assistant → Click and Login with my HA Cloud Creds → Asks “Do you want to allow…” Click Allow → Signing in → Linking starts → Spinning Icon → Error “Couldn’t Update the Settings. Check Your Connection” –

Tried on 3 Androids and iPad - No luck! ANYONE?? (I have searched for hours!)

Thanks
