Custom Post Type and Custom Taxonomy not connected

What is your Custom Taxonomy name?

Try the following code, replace taxonomy_name with whatever your actual taxonomy name is.

$args = array(
    'suppress_filters' => false,
    'numberposts' => -1,
    'post_type' => 'resource',
    'tax_query' => array(
        array(
            'taxonomy' => 'taxonomy_name',
            'field'    => 'slug', //Select taxonomy term by slug( you can also use name/id)
            'terms'    => 'term-slug/category -slug',
        ),

);

$the_query = new WP_Query( $args );
