Scheduler task only firing once

Has there been any changes in the Scheduling system, I have a strange situation where a job has only run once on the day it was created but never again (it should be daily dripsms-dayjob).

Running the CLI commands show when it was last run, and when it is a scheduled to run again but it never seems to trigger as the last run remains the day it was setup.
There’s no errors being reported.

The scheduler is running, as the daily backups is running and updates it’s last run time.

Any ideas on things to check are greatly appreciated.

Best,
Adrian
