I take the exemple from celery repository and I put it to a new empty repository:
https://github.com/celery/celery/blob/main/examples/tutorial/tasks.py

If I use the following command to launch the worker, it's works:
```
celery -A celeryworker.tasks worker --loglevel=info --concurrency=1
```
By works I mean launching the worker without a broker service result on retry.

```
[2026-02-09 09:56:37,557: ERROR/MainProcess] consumer: Cannot connect to amqp://guest:**@127.0.0.1:5672//: [WinError 10061] Aucune connexion n’a pu être établie car l’ordinateur cible l’a expressément refusée.

```
if I add the purge option, it didn't work:
```
celery -A celeryworker.tasks worker --loglevel=info --concurrency=1 --purge
```


```
celery -A celeryworker.tasks worker --loglevel=info --concurrency=1 --purge
