Trouble with Custom Post Type…

I’m creating a custom post type with taxonomies in WordPress 4.7.3, but for some reason the taxonomy pages aren’t working properly. My custom post type is “events”, but the archive-events.php template file isn’t working when visiting “mysite.com/events/event-category” or when visiting “mysite.com/events”

Below is my code from functions.php, what am I doing wrong here??? lol

add_action( 'init', 'register_events', 20 );
function register_events() {
    $labels = array(
        'name' => _x( 'All Events', 'events','sonal' ),
        'singular_name' => _x( 'Event', 'events', 'sonal' ),
        'add_new' => _x( 'Add New', 'events', 'sonal' ),
        'add_new_item' => _x( 'Add New Event', 'events', 'sonal' ),
        'edit_item' => _x( 'Edit Event', 'events', 'sonal' ),
        'new_item' => _x( 'New Event', 'events', 'sonal' ),
        'view_item' => _x( 'View Event', 'events', 'sonal' ),
        'search_items' => _x( 'Search Events', 'events', 'sonal' ),
        'not_found' => _x( 'No Events found...', 'events', 'sonal' ),
        'not_found_in_trash' => _x( 'No Events found in Trash', 'events', 'sonal' ),
        'parent_item_colon' => _x( 'Parent Event:', 'events', 'sonal' ),
        'menu_name' => _x( 'Events', 'events', 'sonal' ),
    );

    $args = array(
        'labels' => __( $labels, 'local' ),
        'hierarchical' => true,
        'description' => 'events',
        'supports' => array( 'title', 'editor', 'excerpt', 'author', 'revisions' ),
        'taxonomies' => array( 'events_category'),
        'show_ui' => true,
        'show_in_menu' => true,
        'menu_position' => 5,
        'menu_icon' => 'dashicons-tickets-alt',

        'exclude_from_search' => false,
        'query_var' => true,
        'can_export' => true,

        'public' => true,
        'has_archive' => 'events_category',
        'capability_type' => 'post'
    );  
    register_post_type( 'events', $args );
}
