Landing in 404 Page on Navigating to Custom Taxonomy Archive

Can you please take a look at this post and let me know how I can navigate to Taxonomy URL properly? Having a CPT called movie and a Taxonomy called genre how I can navigate into archive of taxonomy.php and taxonomy-genre.php

<?php      flush_rewrite_rules( false ); function custom_post_type_movie() {     $  labels = array(         'name'                  => 'movies',         'singular_name'         => 'movie',         'menu_name'             => 'Movies',         'name_admin_bar'        => 'Post Type',         'archives'              => 'Item Archives',         'attributes'            => 'Item Attributes',         'parent_item_colon'     => 'Parent Item:',         'all_items'             => 'All Items',         'add_new_item'          => 'Add New Item',         'add_new'               => 'Add New',         'new_item'              => 'New Item',         'edit_item'             => 'Edit Item',         'update_item'           => 'Update Item',         'view_item'             => 'View Item',         'view_items'            => 'View Items',         'search_items'          => 'Search Item',         'not_found'             => 'Not found',         'not_found_in_trash'    => 'Not found in Trash',         'featured_image'        => 'Featured Image',         'set_featured_image'    => 'Set featured image',         'remove_featured_image' => 'Remove featured image',         'use_featured_image'    => 'Use as featured image',         'insert_into_item'      => 'Insert into item',         'uploaded_to_this_item' => 'Uploaded to this item',         'items_list'            => 'Items list',         'items_list_navigation' => 'Items list navigation',         'filter_items_list'     => 'Filter items list',     );     $  args = array(         'label'                 => 'movie',         'description'           => 'Post Type Description',         'labels'                => $  labels,         'supports'              => array( 'title', 'editor' ),         'taxonomies'            => array( 'genre' ),         'hierarchical'          => false,         'public'                => true,         'show_ui'               => true,         'show_in_menu'          => true,         'menu_position'         => 2,         'show_in_admin_bar'     => true,         'show_in_nav_menus'     => true,         'can_export'            => true,         'has_archive'           => true,         'exclude_from_search'   => false,         'publicly_queryable'    => true,         'capability_type'       => 'page',     );     register_post_type( 'movie', $  args );  } add_action( 'init', 'custom_post_type_movie', 0 );   function genre() {      $  labels = array(         'name'                       => 'Movie Genres',         'singular_name'              => 'Taxonomy',         'menu_name'                  => 'Genre',         'all_items'                  => 'All Items',         'parent_item'                => 'Parent Item',         'parent_item_colon'          => 'Parent Item:',         'new_item_name'              => 'New Item Name',         'add_new_item'               => 'Add New Genre',         'edit_item'                  => 'Edit Item',         'update_item'                => 'Update Item',         'view_item'                  => 'View Item',         'separate_items_with_commas' => 'Separate items with commas',         'add_or_remove_items'        => 'Add or remove items',         'choose_from_most_used'      => 'Choose from the most used',         'popular_items'              => 'Popular Items',         'search_items'               => 'Search Items',         'not_found'                  => 'Not Found',         'no_terms'                   => 'No items',         'items_list'                 => 'Items list',         'items_list_navigation'      => 'Items list navigation',     );     $  args = array(         'labels'                     => $  labels,         'hierarchical'               => true,         'public'                     => true,         'show_ui'                    => true,         'show_admin_column'          => true,         'show_in_nav_menus'          => true,         'show_tagcloud'              => true,     );     register_taxonomy( 'genre', array( 'movie' ), $  args );  } add_action( 'init', 'genre', 0 ); ?> 

In my theme directory I have 3 files for taxonomy like

enter image description here

in each of them I have code like

<?php get_header(); ?>  <main id="main" class="site-main" role="main">     <?php      if ( have_posts() ) :          while ( have_posts() ) : the_post();              // Display post content             the_title();         endwhile;      endif;      ?> </main>  <?php get_footer(); 

in both http://wpdev/genre and http://wpdev/movie/genre I am landing in 404 page
