Wordpress page-template foreach json not working

It seems there has been a PHP update that I don't know about

In the page-template folder of the theme (made by me custom) there is a file to put a custom template to put six cards whose data I take from a json file through a Foreach loop.

The Foreach loop worked before but now it doesn't work. Maybe it's a PHP update that I'm not aware of.

Replacing the cards I put six identical texts

You can see this here The text above is entered directly into the wordpress editor

This is the code:

<?php 
/* Template Name: Cards Principal */
?>
<?php get_post(); ?>
<?php get_header(); ?>
<hr>
<h2 class="pageTitle"><strong><?php the_title(); ?></strong></h2>
<hr>
<?php the_content(); ?>

<?php 
$miJSON = file_get_contents('https://2000peliculassigloxx.com/wp-content/uploads/json/principal.json');
$datos = json_decode($miJSON, true);

echo '<div class="container-fluid">';
echo '<div class="row row-cols-1 row-cols-sm-2 row-cols-md-3 g-4">';
echo '<strong>TARJETA EN MANTENIMIENTO</strong>';
echo '<strong>TARJETA EN MANTENIMIENTO</strong>';
echo '<strong>TARJETA EN MANTENIMIENTO</strong>';
echo '<strong>TARJETA EN MANTENIMIENTO</strong>';
echo '<strong>TARJETA EN MANTENIMIENTO</strong>';
echo '<strong>TARJETA EN MANTENIMIENTO</strong>';
foreach($datos as $dato){
echo '<a href="'.$dato['Enlace'].'" target="_blank">';
echo '<div class="card text-center">';
echo '<img src="'.$dato['url_imagen'].'" class="card-img-top"  alt="'.$dato['Título'].'">';
echo '<div class="card-body">';
echo '<h3 class="card-title">'.$dato['Título'].'</h3>';
echo '<p class="card-text">'.$dato['Texto'].'</p>';
echo '</div>';
echo '</div>';
echo '</a>';
}
echo '</div>';
echo '</div>';
?>

<?php get_footer(); ?>

Please I need all six cards to be seen
