Query post if has two of the categories

I'm banging my head here. I can't seem to figure out what's wrong with this it works although if a post has more than two categories is doesn't seem to show. What is wrong here?

<div class="base-column">
                        <button class="accordion">How To&nbsp;&nbsp;&nbsp;<img src="/wp-content/uploads/sites/2/2018/11/expand-button.jpg"></button>

                                'post_type'     =>  'post',
                                'category__and' => array(117,123),
                            );

                            // The Query
                            $the_query_1 = new WP_Query( $args_1 ); ?>

                            <?php // The Loop
                            if ( $the_query_1->have_posts() ) {

                                wp_reset_postdata();
                            } else {
                                // no posts found

You need to edit line 7.

'category__and' => array(117,123),

The category__and parameter doesn't use a string for the category IDs. Write the array like this:

    'category__and' => array(
        '117',
        '123'
    )
);
