Celery lost connection to broker

[AlessandroSalvetti]

Hi, I'm using rabbitmq 3.13.0 Erlang 26.2.2 rabbitmq-message-deduplication 0.6.2

celery 5.3.6 django-celery-beat 2.6.0

When the the argument x-message-deduplication is set to true for the celery queue, then all the messages sent to the queue causes celery to lost the connection:

consumer: Connection to broker lost. Trying to re-establish the connection...
Traceback (most recent call last):

What it could be?
