Node statisics or Queue information not available in the cluster node.

[Anmol Vijaywargiya]

I have a 5 node rabbitmq cluster running on rabbitmq version 3.8.5, erlang version 21.3.
I add a 6th node into the cluster running on rabbitmq version 3.8.27 erlang version 24.2.2
There's an issue w.r.t the management UI.
Management UI of the existing cluster

Node statistics of the 6th node rabbit@g-lambda-lambda-rabbitmq-rabbitmq-a-2002 aren't available.

Management UI of the new node

Node statistics of only the 6th node i.e. rabbit@g-lambda-lambda-rabbitmq-rabbitmq-a-2002 are available.

Also, a similar issue is seen with the queues page as well. The information for the queues for which the 6th node (rabbit@g-lambda-lambda-rabbitmq-rabbitmq-a-2002) is the leader, shows up as NaN in the management UI of the existing cluster.

While the management UI of the 6th node only shows the information for the queues for which it is the leader and NaN for the rest.

A similar issue was also posted by someone else on StackOverflow in 2021 but didn't find a concrete answer to it.

Does anyone have an idea on how to fix this?
