Couldn't connect Home Assistant to my Google Home

I removed my Home Assistant connection with my Google Home because of some updates of exposed domains within Home Assistant.

Only now for some reason I can’t add my Home Assistant to my Google Home.
I see the project within the Google Home App but when I add the project I see the login page and once all my details are filled in in I recieve the message from Google

"401. That’s an error.

Your client doees not have permission to the requested URL /services/auth/handoffs/auth/complete?state=Col…
That’s all we know.
"

Any thoughts around this issue?

Fixed it, due to a caching issue on my iPhone, after emptying my history and cache from Safari I was able to connect Google Home.
