I’m on Kirby 2.3 and trying to get a blueprint field to accept JSON options, as described in the [docs](https://getkirby.com/docs/cheatsheet/panel-fields/checkboxes). My setup is the same as the docs:

```
title: Last name letter
pages: true
files: false
fields:
    title:
        label: Letter
        type: text
    category:
        label: Category
        type: checkboxes
        default: architecture
        options: http://192.168.1.141/dvddb/directorapi/api.json

```

api.json is:

```
{
  "id": "Design",
  "architecture": "Architecture",
  "photography": "Photography",
  "3d": "3D",
  "web": "Web"
}

```

Yet no checkboxes are displayed when editing the page. Why would that be?

The URL probably does not validate:

```auto
public function isUrl($url) {
    return
      v::url($url) or
      str::contains($url, '://localhost') or
      str::contains($url, '://127.0.0.1');
  }

```

Although it should. Can you test on a remote url if it is the validator or something else? Or try localhost?

**Update** : just tested this on my system and when I call [http://192.xxx/](http://192.xxx/)… it does not work either, while localhost does.

You are right, replacing the IP with localhost resolves the problem. Thank you!
