Opencast not populating SMP's and 2 workflow jobs pending for some time now

[sigapb]

While we successfully extract out teaching timetable onto opencast, it is not populating our SMP's
A few abnormal behaviors:

1. I have 2 workflow jobs that have been running since Friday 6th March
2. 3067214 | Queued | START_OPERATION | org.opencastproject.workflow |   |   | 3/6/26 6:28 PM |   | opencast_system_account
   3067215 | Queued | START_OPERATION | org.opencastproject.workflow |   |   | 3/6/26 6:44 PM |   | opencast_system_account
3. All running processes are still on running mode since Friday

Have tried restarting services and servers without success. Below is as snippet of the opencast log file

We running opencast 14.13.0

The lines about being unable to dispatch a job are the clue: whatever service that the workflow is looking for is missing or down. Specifically job 3067214's type would tell you. In the database, that number is the id for the job in job table.

Thank you very much. It was a certificate expiration issue that rendered a few services to be unreachable.
