Google Assistant Manual Configuration - Fail to Link to Google Home

I have tried to follow the instructions here: Google Assistant - Home Assistant

I keep getting stuck on step 5. When selecting my action in the google home app, I get the message ‘Could not reach [test] Home Assistant. Please try again.’

As far as I can tell I have external access to my HA instance configured correctly. I can reach it in a web browser and via the app.

Has anyone ran into this before? I can’t find logs of any sort (related to this integration) to troubleshoot this further.

I am thinking I forgot to restart Home Assistant. Restarted it today and its working now.
