Nest Integration Error 400

I am trying to integrate my Nest Camera… I have followed the tutorial and keep getting this error: Snip 1 . I am using the Nabu Casa address in my Oauth. Not the internal url…

What am I missing?

You have to be looking at HA via the external URL when you click the button to connect to Nest. When you click the button it creates the redirect URI and passes it to google by looking at the URL you are currently on. So to get it to use the nabu casa address as the redirect URI you have to be looking at HA via the nabu casa address, not a local-only one.
