Problem with cron

[DaaN88]

Hi, there is such a cron:
*/15 0-8,21-23 * * *
And i get the error:
Failed to parse the following CRON expression: */15 0-8,21-23 * * * {"userId":205,"exception":"[object] (Lorisleiva\CronTranslator\CronParsingException(code: 0): Failed to parse the following CRON expression: */15 0-8,21-23 * * * at /var/www/vendor/lorisleiva/cron-translator/src/CronTranslator.php:33)
How to fix it?
On https://crontab.guru/ such this cron is recognized...
