No Alert to show in Alerts page when the job has failed.
Note: Making DB changes should be done with extreme caution. Take a backup before making the recommended changes.
The internal job might stuck in blocking state which could cause this issue. Check the below conditions,
- Robot role and make sure the user has the permission to view and create the Alert
- Table qrtz_trigger. If the status of notification is 'blocked', need to update the DB by using the following SQL and restart the IIS server.
UPDATE QRTZ_TRIGGERS SET TRIGGER_STATUS = 'WAITING' WHERE TRIGGER_NAME = 'NotificationDistributerJob'
