How is the archive.php of your own theme looks like? Are you creating your theme based on underscore? You probably missing the get content part after the pagination. For example, here is part of the archive.php based on underscore theme:
if ( have_posts() ) : ?>
<header class="page-header">
<?php
the_archive_title( '<h1 class="page-title">', '</h1>' );
the_archive_description( '<div class="taxonomy-description">', '</div>' );
?>
</header>
<?php
while ( have_posts() ) : the_post();
get_template_part( 'components/post/content', get_post_format() );
endwhile;
the_posts_navigation();
else :
get_template_part( 'components/post/content', 'none' );
endif; ?>
