WordPress PHP error getting posts from another wor

I'm using this code in the template-blog.php page of my website, to get posts from my first WP blog to the second WP blog, different websites using the same blog posts.

this code has been working great for years, but suddenly it stopped working giving me invalid argument foreach on line 133

it gives an error on this part

<?php
//$url = 'https://www.FIRSTWP.com/wp-json/wp/v2/posts/';
$url = 'https://www.FIRSTWP.com/wp-json/posts/';
$response = wp_safe_remote_get( $url );
if ( ! is_wp_error( $response ) ) {
    $remote_post = json_decode( wp_remote_retrieve_body( $response ) );
    //echo "<pre>";
    //print_r($remote_post[0]);
    //echo "</pre>";
                    //echo '<h3><a href="' . esc_url( $remote_post[0]->link ) . '">' . esc_html( $remote_post[0]->title ) . '</a></h3>';

                    //remote post's content
                    //echo '<p>' . wp_kses_post( $remote_post[0]->content ) . '</p>';

?>

<?php foreach( $remote_post as $remote_single_post){ ?>
<article id="post-1" class="post-1 post type-post status-publish format-standard hentry category-uncategorized">
                        <header class="entry-header">
                                                        <h1 class="entry-title"><a href="<?php echo esc_url( $remote_single_post->link ); ?>" title="Permalink to Hello world!" rel="bookmark" target="_blank"><?php echo esc_html( $remote_single_post->title ); ?></a></h1>

                                                    </header><!-- .entry-header -->

                                                <div class="entry-content">
                                                <div  class="api_content"><?php echo '<p>' . wp_kses_post( $remote_single_post->content ) . '</p>'; ?> </div>

                        </div><!-- .entry-content -->


                                                                                                                <span class="cat-links">

                          <?php foreach( $remote_single_post->terms->category as $api_category){ ?>
                          <a href="<?php echo esc_html ($api_category->link)?>" rel="category tag" target="_blank"><?php echo esc_html ($api_category->name)?></a>, <?php } ?>                  
                            </span>

I'm not sure what is causing the problem is it has been working fine for years now, so any help would be appreciated
