Failed to fetch baseUrl

I am unable to fetch data from the WordPress url. I simply put the url of the WordPress website in the **baseUrl** field.
The error says:
>Error: Failed to fetch baseUrl https://discover.wordpress.com/
at WordPressSource.fetchWordPressContent (Z:\My Work\Projects\sample-project\node_modules\@gridsome\source-wordpress\index.js:33:13)
at
at process._tickCallback (internal/process/next_tick.js:188:7)

Here's the code in gridsome.confg.js:
```javascript
module.exports = {
siteName: 'Gridsome',
siteDescription: 'A WordPress starter for Gridsome',
plugins: [
{
use: '@gridsome/source-wordpress',
options: {
baseUrl: 'https://discover.wordpress.com/', // required
typeName: 'WordPress', // GraphQL schema name (Optional)
perPage: 3, // How many posts to load from server per request (Optional)
concurrent: 10, // How many requests to run simultaneously (Optional)
routes: {
post: '/:year/:month/:day/:slug', //adds route for "post" post type (Optional)
post_tag: '/tag/:slug' // adds route for "post_tag" post type (Optional)
}
}
}
]
}
```

Everything else is the same as in the **gridsome WordPress starter template**.
