I can’t log in user !

WordPress returns false to wp_validate_auth_cookie .
I get only these cookies (each generated by wp-admin and /wp-content/plugin):

• wordpress_e929v…
• wordpress_sec_e929v….

I don’t have these cookies:

• wordpress_logged_in
• wp-settings-time-1
• wp-settings-1
• wordpress_test_cookie
• wp_lang

My php code :

add_action('wp_ajax_atv_user_login','handle_user_login');
add_action('wp_ajax_nopriv_atv_user_login', 'handle_user_login');


function handle_user_login(){
    check_ajax_referer( 'ajax-login-nonce', 'security' );
    
    $log_param = isset($_REQUEST['log-param'])?trim($_REQUEST['log-param']):"";
    if($log_param == "login_data" ){
        $info = array();

        $info['user_login'] = $_POST['user_login'];
        $info['user_password'] = $_POST['user_pass'];
        $info['remember'] = true;
        $user = get_user_by( 'login', $info['user_login']);
        if ( $user && wp_check_password( $info['user_password'], $user->data->user_pass, $user->ID ) ) {
            $isActivated = get_user_meta($user->ID, 'is_activated', true);
        }
        $user_signon = wp_signon($info, false);
        $data = array();
        
        if(is_wp_error($user_signon)){
            $error_string = $user_signon->get_error_message();
            $data['status'] = array(0);
        }else{
            if(intval($isActivated) != 1){
                $data['useremailauth'] = array('Send email to auth');
            }else if(intval($isActivated) == 1){
                $data['status'] = array(1);
                clean_user_cache($user->ID);                
                wp_set_current_user($user->ID);
                wp_set_auth_cookie($user->ID, true, is_ssl());
                wp_user_settings($user->ID);
                //setcookie('useratv','connected', time() + (3600), "/"); 
                update_user_caches($user->ID);
                
                if(!($user = wp_validate_auth_cookie($_COOKIE[LOGGED_IN_COOKIE], 'logged_in'))){
                    $data['islogin'] = "no login";
                }
                
                if(is_user_logged_in()){
                    $current_user = wp_get_current_user();
                    $userpicture = "test";
                    $data['userpicture'] = array($userpicture);
                }
