Event created not executed and status became "DISABLED"

[NPO CNHi Support]

Good morning,
i am facing this issue:
i am trying to create an event that trigger a stored procedure but after the time set arrive the event change from ENABLED to DISABLED and the store procedure is not triggered.
The event scheduler is ON obviously:


mysql> select @@global.event_scheduler;
+--------------------------+
| @@global.event_scheduler |
+--------------------------+
| ON |
+--------------------------+
1 row in set (0.00 sec)

DROP EVENT IF EXISTS run_qlik_refresh;
SET GLOBAL event_scheduler = ON;
CREATE EVENT run_qlik_refresh ON SCHEDULE AT '2020-08-03 15:15:00' DO CALL qlik_refresh();
COMMIT;

Does anybody every faced this problem or has a clue on how to solve it?
Thank you.
