Show posts from selected month

I have an archive-news.php file to show posts from a custom post type called news.

On the sidebar, I created an archive list wich group post by month. This is the output:

<h4>2014</h4>
	<ul class="archive-list">
		<li><a href="/website/2014/04">april <span class="count">(1)</span></a></li>
		<li><a href="/website/2014/03">march<span class="count">(6)</span></a></li>
        </ul>

But when I click in some month, I got page not found.

I can use the same archive-news.php to show the post in accordance with the selected month?
