Google Assistant - Unable to link app?

So, i’m got through the whole setup, SSL working, Google actions app setup etc, using these docs:

I’m now on the last step of adding the “device” to Google home, I see it “[test] Smart Home Control”, when i click to add it, it takes me to an oauth2. page, then redirects back to the Home app, briefly at the bottom it flashes up and says:

“Linking your [test] smart home control account”

Then at the bottom it says “Couldn’t update the setting. Please check your connection”

Can anyone advise?

There is already a thread about this exact issue

Well no because that thread was posted after mine :slight_smile:

However I will track that one as it got more replies.
