Navigation links only detected for the first page

I have a blog with the Polylang plugin installed. When I tried to convert it with WP2Static almost everything worked, except for the navigation links in the footer. My site has them similar to this

`1 2 ... 26 Previous posts`

which redirect to /es/page/2, ... /es/page/26,

The crawl seems to detect only 1, 2, and 26. So if I hit "Previous posts" on page 2, it should redirect to /es/page/3 but this URL doesn't seem to be crawled and returns a 404.

Edit: the live blog is hosted at https://blog.hjf.com.ar and the static version at http://sblog.hjf.com.ar.s3-website-sa-east-1.amazonaws.com/
