### Widget Assets

Make sure that static assets required by the ChatWidget are accessible. These are typically served from:
Make sure that all static and media assets the widget loads are accessible. The widget pulls from four paths:

```
https://yourdomain.com/packs
https://yourdomain.com/vite/assets
https://yourdomain.com/brand-assets
https://yourdomain.com/rails/active_storage
```

Ensure all paths under this directory are accessible to support the widget fully.
- **`/packs`** — the SDK loader script (`packs/js/sdk.js`) embedded into the parent page.
- **`/vite/assets`** — JavaScript and CSS bundles loaded inside the widget iframe. Chatwoot migrated this UI from Webpack to Vite, so older guides referring only to `/packs` are incomplete for newer deployments.
- **`/brand-assets`** — installation-level branding (logo, favicon) shown inside the widget.
- **`/rails/active_storage`** — image and file attachments. Used for both visitor uploads and any media the agent sends back. Without this, attachments display as broken images on the visitor side.

All four paths must be publicly accessible to support the widget fully.

### Widget Page

The Chatwoot SDK loads the chat UI by injecting an iframe whose `src` points to `/widget`. This path must also be publicly accessible for the widget to render:

```
https://yourdomain.com/widget
```

Without this, the SDK script loads correctly but the iframe fails to load, resulting in a missing chat bubble. This commonly affects deployments behind authentication gateways such as Cloudflare Access, basic auth, or other ZTNA proxies.
