Html helper link to nested resource Routes

I have the following route:

$routes->resources('Articles', function ($routes) {
    $routes->resources('Comments');
});

I want to link to all comments of the article with id 4: 

articles/4/comments

How can I create a link to this url with cakes HtmlHelper?

Look at the example route patterns given in the linked docs, the nested Articles > Comments resources will create routes for Comments with the following patterns:

/articles/:article_id/comments
/articles/:article_id/comments/:id

You can also check $ bin/cake routes to get a list of all connected routes with their patterns and defaults. The route you're looking for will be listed there as something like this:

+----------------+--------------------------------+--------------------------------------------------------------------------+
| Route name     | URI template                   | Defaults                                                                 |
+----------------+--------------------------------+--------------------------------------------------------------------------+
| comments:index | /articles/:article_id/comments | {"controller":"Comments","action":"index","_method":"GET","plugin":null} |

All resource routes are bound to specific HTTP methods (as can be seen above in the defaults column), ie internally the _method option is used, and the parent ID is prefixed with the singular controller/resource name.

To match the Comments index, simply target the Comments controller and index action as usual. Additionally pass the corresponding _method (for index that's GET), and pass the parent ID in a named fashion, ie as article_id, like:

[
    'controller' => 'Comments',
    'action' => 'index',
    '_method' => 'GET',
    'article_id' => 4
]

You could join Html and Url helpers, like this:

<?= 
    $this->Html->link(
        'Enter',
        $this->Url->build('/articles/4/comments', true),
        ['class' => 'button', 'target' => '_blank']
    ); 
?>
