Celery workers not running prevents task execution

Celery workers are not started or have stopped, preventing any task processing and causing Flower monitoring to show no active workers

Check worker status with `celery -A <my_app_name> status`. If no workers are listed or errors appear, start workers with `celery -A <my_app_name> worker --loglevel=info`. Verify workers are connected and processing tasks before starting Flower.
