My celery-beat works locally but not in production? - django

Question

my task:
#shared_task
def my_test():
# Executes every 2 minutes
UserStatisticStatus.objects.filter(id=1).update(loot_boxes=+234)
print('Hello from celery')
app.conf.beat_schedule = {
'my-task-every-10-seconds': {
'task': 'user_statistic_status.tasks.my_test',
'schedule': timedelta(seconds=10)
}
}
my settings:
if 'RDS_DB_NAME' in os.environ:
CELERY_BROKER_URL = 'redis://<myurl>/0'
CELERY_ACCEPT_CONTENT = ['application/json']
CELERY_RESULT_SERIALIZER = 'json'
CELERY_TASK_SERIALIZER = 'json'
CELERY_BROKER_TRANSPORT_OPTIONS = {
'region': 'eu-central-1',
'polling_interval': 20,
}
CELERY_RESULT_BACKEND = 'redis://<myurl>/1'
CELERY_ENABLE_REMOTE_CONTROL = False
CELERY_SEND_EVENTS = False
CELERY_TASK_ROUTES = {
'my_test': {'queue': 'default'},
}
my celery.py :
import os
from celery import Celery
from project import settings
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings')
app = Celery('celery_app')
app.conf.task_routes = {
'my_test': {'queue': 'default'},
}
app.config_from_object('django.conf:settings', namespace='CELERY')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

It gets stuck here and task never executes !!!
The worker connects and shows the tasks correctly and the beat starts too but nothing happening. I've tested it with the local redis server and everything works fine.
Any help will be much appreciated
Thank you
