Cron schedule not updating after run

You can use wp-cli to execute schedules without the detour via http request. Add in crontab -e.

*/30 * * * * wp cron event run --path=/path/to/wp-docroot

By this you wont run into maximum execution time problems which could be the reason why you schedule execution got stuck.
