WP cron Executes once and doesnt repeat

Question

Might be a bad question but im unable to solve it right now.

My WP_cron executes on the starting point but doesn't seem to perform afterwards.

My functions.php code is:

 add_action( 'my_scheduled_event', 'prefix_my_scheduled_event' );

 if(!wp_next_scheduled('my_scheduled_event')){
   $timestamp = strtotime( '2017-09-28 12:05:00' ); 
   $recurrence = 'twicedaily';
   $hook = 'my_scheduled_event';
   wp_schedule_event( $timestamp, $recurrence, $hook );
 }

Additionaly i have added this line to wp-config.php to make it work in the first place.

 define('ALTERNATE_WP_CRON', true);

Any suggestions are welcome.

This can happen if your server is overloaded on a shared host. Check your server logs or resource use in c-panel. It can also be limited by your host depending on the server configuration.
