WordPress cron not working, why?

Question

Task Schedulers

There is a server with ISPmanager installed on it.
A website is launched on it, an online store (Woocommerce), there is a purchased plugin that parses goods from a third-party store, the plugin works on a cron, every 5 minutes it takes a pack of goods and imports. So in the plugin settings it is indicated that the cron does not work on this server, but on the other it gets up normally and immediately works. I created a post delayed for one minute, it was not published, I think that the problem is that the WordPress cron does not work, I tried the alternative version, it did not help, I turned off the cron altogether and made requests through the server scheduler, (wp-cron.php? doin... .) does nothing.
Apparently I missed something in setting up the server?
