Google Assistant Integration Fails in 2021.7.2

Just upgraded to the latest version of Core and OS on my Pi. I put in the HTTP config before and I can remotely access the UI, however Google Assistant can no longer login and I get this notification:

Login attempt failed
Login attempt or request with invalid authentication from ( See the log for details.

I don’t know where the log this notification speaks of resides, so I haven’t been able to check it.

Here is my YAML for the HTTP:

  server_port: 8123
  use_x_forwarded_for: true
    - #This is my NGINX reverse proxy server
  ip_ban_enabled: false
  login_attempts_threshold: 100

Can anyone point me in the right direction to get it going again?

Just had to reconnect Home Assistant via the Google Home app. Must have used Trusted Network before and now the new setup rightfully stops this so needed my external password
