When using a remote custom connector in Claude for Desktop, the connection is brokered through Anthropic's cloud infrastructure. This means your Home Assistant instance must be publicly accessible from the internet.

{% note %}
Use the same URL that is configured as your Home Assistant external URL. If you use [Home Assistant Cloud](/integrations/cloud/), use your Nabu Casa Cloud URL (for example, `https://<your_id>.ui.nabu.casa`). Connecting with a different URL, such as an internal split-horizon domain, can cause the login step to fail with a blank 404 page, because Home Assistant builds the OAuth redirect from the configured external URL. You can check or update this URL at {% my network title="**Settings** > **System** > **Network**" %}.

So above we say "This means your Home Assistant instance must be publicly accessible from the internet". and below we says <your_home_assistant_external_url>.

Perhaps we can edit one of these points and link to https://www.home-assistant.io/docs/configuration/remote/ if users don't know what their external URL is?
