Cannot promote queue when home node is down

[polaris-alioth]

I have a mirrored queue named testeat, the master node is rabbitmq-1 and slave node is rabbitmq-0.

rabbitmq-0 and rabbitmq-1 instances is down successively
When I started the rabbitmq-1. The queue is in down status.

Cannot promote the queue when home node is down.

We cannot suggest much with the amount of information provided. See node logs for clues.

On the second screenshot, there are no mirrors for the queues. This can be due to no mirrors being synchronised or another reason. Again, there isn't enough information to tell, see node logs for clues. All cases involving no promotable mirrors are logged.

RabbitMQ documentation explicitly suggests that two node clusters is an unsupported configuration and that classic queue mirroring is deprecated in favor of quorum queues that require an online majority of replicas (and thus 3 or more nodes).

This is my rabbitmq.conf：
cluster_partition_handling = autoheal
I set the policy like below, expected that when home node is down, the other node will be promoted to be master.
rabbitmqctl set_policy -p / ha-allqueue "^" {"ha-mode":"all","ha-sync-mode":"automatic","ha-promote-on-shutdown":"always"}
Below is the logs:
