Run Email Reminder Notifications successful but no email

Dear all,

I have a SuiteCRM with the version below:
Version 7.11.18
Sugar Version 6.5.25 (Build 344)

I am able to run the report scheduler and receive emails with reports.

For the Run Email Reminder Notifications job, the status shows “Done” but I am not able to receive any email reminder (mainly on the Contracts Reminder). I tried to schedule it every 1 min, 5 minutes, 10 minutes and 30 minutes, still no email.

From the suitecrm.log, the following is the log:

 SET `assigned_user_id`='1',`name`='Run Email Reminder Notifications',`date_modified`='2020-06-03 21:03:02',`scheduler_id`='97dbdc94-2c64-6270-21c4-59d05a9d4227',`execute_time`='2020-06-03 21:00:00',`status`='running',`resolution`='queued',`message`=NULL,`target`='function::sendEmailReminders',`data`=NULL,`requeue`=0,`retry_count`=NULL,`failure_count`=NULL,`job_delay`=0,`client`='CRONe4e33953b1b5c4c210dfe2728b2e8b81:6915',`percent_complete`=NULL

Please advise is there anything that I have missed.

Thank you in advance.

Best Regards,
