Connection showing one only of multiple sentinel servers defined

[dan-developer]

• Python 3.12.9
• Celery 5.3.1
• Kombu 5.3.2

When I configure multiple sentinels to celery broker, when celery starts show only one of this sentinels.

I configured following documentation: https://docs.celeryq.dev/projects/kombu/en/stable/userguide/connections.html#urls

So, I did an example code to test:

      with Connection('sentinel://0.0.0.0:26347/3;sentinel://0.0.0.0:26348/3') as conn:
          print(conn.as_uri())

This output the following: sentinel://0.0.0.0:26347/3
And not show the another two sentinels defined.

Trying with another option, in this case, amqp:

      with Connection('amqp://foo;amqp://bar') as conn:
          print(conn.as_uri())

This output the following: amqp://guest:**@foo:5672//
And not show the another two amqp defined.

I've read the kombu code to make sure that I thinking correctly:

class SentinelChannel(Channel):
    """Channel with explicit Redis Sentinel knowledge.

    Broker url is supposed to look like:

    .. code-block::

        sentinel://0.0.0.0:26379;sentinel://0.0.0.0:26380/...

    where each sentinel is separated by a `;`.

    Other arguments for the sentinel should come from the transport options
    (see `transport_options` of :class:`~kombu.connection.Connection`).

    You must provide at least one option in Transport options:
     * `master_name` - name of the redis group to poll

    Example:
    -------
    .. code-block:: python

        >>> import kombu
        >>> c = kombu.Connection(
             'sentinel://sentinel1:26379;sentinel://sentinel2:26379',
             transport_options={'master_name': 'mymaster'}
        )
        >>> c.connect()
    """

Could you help me?

can you reproduce it with celery 5.5.x?
