I have custom post type 'coupons':

    $args = array(
        'label' => __('Купоны', 'sp'),
        'labels' => $labels,
        'supports' => array('title', 'custom-fields', 'revisions', 'thumbnail', 'excerpt'),
        'hierarchical' => true,
        'public' => false,
        'show_ui' => true,
        'menu_position' => 2,
        'show_in_admin_bar' => true,
        'has_archive' => true,
        'capability_type' => 'post',
        'rewrite' => array('slug' => 'coupons', 'with_front' => false)

    );
    register_post_type('coupons', $args);

I have custom taxonomy 'sategory':

    $args = array(
        'hierarchical' => true,
        'labels' => $labels,
        'show_ui' => true,
        'show_admin_column' => true,
        'query_var' => true,
        'rewrite' => array(
            'slug' => 'sategory',
            'with_front' => false),
    );
    register_taxonomy('sategory', array('coupons'), $args);

When i open "example.com/sategory/tax1" 404 error. File taxonomy-sategory.php created. What could be the problem?

To expand upon what @KrunalBhimajiyani said, whenever you create a CPT or taxonomy, or edit those in a way that the URL structure would change, you need to “flush the permalinks”.

2. Conditionally calling flush_rewrite_rules when a change happens (Not always! You need to either just remove it when done or store a version key or similar in options.)
3. Using the WP-CLI command: wp rewrite flush (optionally with the --hard parameter
