I have the same issue. I do not use Nabu Casa, but a Reverse Proxy and a custom app in dev.netatmo.com. I added the reverse proxy configuration to the http integration and added my URL under Settings->Network->Home Assistant URL. The exposed port to the Internet is 443. I followed the steps to unban my webhook, since it has been banned.
In the following logs I replaced sensitive information
unregister:

The Light Switch in the Dashboard stays grey. I tried to call the Set Light-Mode service, but the light does not turn on:
