Wordpress pagination. Sees pages, but does not want to open - 404?

Question

WordPress

Hi all. I've blown my brains out already. On a normal /rent page, I output a cycle with posts through WP_Query. Knowingly passing there paged defined with

<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; ?>

And I'm trying to display pages using this self-written code:

<?php if ($query->max_num_pages > 1) : ?>
  <div class="content-panel-body pagination">
    <?php if ($paged > 1) : ?>
      <a class="prev page-numbers" href="/rent/page/<?php echo $paged - 1; ?>"><i class="fa fa-angle-left"></i>Назад</a>
    <?php endif; ?>
    <span class="page-numbers current"><?php echo $paged, ' из ', $query->max_num_pages; ?></span>
    <?php if ($paged != $query->max_num_pages) : ?>
          <a class="next page-numbers" href="/rent/page/<?php echo $paged + 1; ?>">Вперёд<i class="fa fa-angle-right"></i></a>
    <?php endif; ?>
  </div>
<?php endif; ?>

It shows that 1 of 4 pages > Forward. I press forward. A 404 page opens. That's it. Help what is the problem.
update: Problem solved. There was a name mismatch. The page (rent) on which records of the rent type were displayed. Output was displayed, and a discrepancy with pagination occurred. Changed the page to rental.
