Home_assistant 404 not found

Hey all,

So I’ve been trying to setup HA and google_assistant but have been hitting a brick wall.
I’m running HAOS with supervisor and pushing it through an NGINX reverse proxy.

I believe the issue is that the URL: https://ha.myDomain.com/api/google_assistant results in a “404: Not Found” error. I tried hitting it directly using the IP address: which returns the same result so I don’t believe it’s a proxy issue. The /auth/authorize URLs still behave as expected so I believe its something related to google_assistant specifically. Is there a step i’ve missed like enabling the google_assistant addon or something?

I’ve searched around and not been able to find anyone having a similar issue. Does anyone know why this might be happening?

Did you already set Google assistant in your config? The url won’t work until that is complete and after reboot.

That was it, I jumped the gun without putting the config in.

hmm, in my case the google yaml config is loaded, but when i browse to :


i also get 404 not found , verry strange

any idea?

google_assistant: !include google.yaml

and in google.yaml

  project_id: !secret google_proj
  service_account: !include hassio-xxx.json
  expose_by_default: false
  report_state: true

hmm, seems if i rollack to 2021.12.x , i get back 405 , so can link again

if i update to 2022.2.1 , i get 404

what do you get now on release 2022.2.x ?
