I believe when you signed up you were given a link to access it externally and you have to enter that into your companion app as your server address and then there's an option to enter the internal IP address and your SSID so that when you are on Wi-Fi it will just go directly to it instead of using the external link.

@bazcurtis @homeassistant@fosstodon.org @homeassistant@lemmy.world @homeassistant@a.gup.pe @homeassistant@chirp.social in the URL setting there should be an option for Internal URL and external URL. Internal you need to set your SSID that is internal. And external should be able to just turn on Home Assistant Cloud.
