6027-3957 [N] Connection from node in cluster cluster rejected
because it uses IPv6 but IPv6 is not enabled in the local cluster.
Explanation
A connection request was received from a node that uses IPv6 as its primary address,
but IPv6 is not enabled in the local cluster. Since local nodes in the local cluster may not be able
to communicate with the joining IPv6 node, it is not permitted to join the local
cluster.
User response
Enable IPv6 in the local cluster or change all nodes using IPv6 as their primary
addresses to use IPv4 addresses in the joining cluster.
