Access control in Synology NAS and voice command with Google Assistant

Hi

I have a DS423+ and I have an issue with access control.

I have a raspberry Pi hosting a Home Assistant instance. I use reverse proxy on the Synology NAS to access Home Assistant. To secure this, I use access control to only allow some IP adresses. However, on Home Assistant, I set up a link between Home Assistant and Google Home with this tutorial : Google Assistant - Home Assistant (home-assistant.io) (manual setup).

With access control, Google Home and Home assistant can’t communicate. How can I allow these requests to Home Assistant ?

Thank you

Hey, did you ever get this to work?
I have mostly the same problem as you.
I use the synology reverse proxy and tried to make sense of the outdated Home Assistant manual set up guide. But when I try to connect to the app from Google Home, I just get an error without any context.
