Entrust PKI Hub only supports IPv4 and disables IPv6 by default. In multi-node deployments, all nodes:

  • Must have a fixed hostname and IP address.
  • Must be in the same subnet, cloud region, or virtual network.

After the installation, run the following command in each node to check the IP address and subnet mask.

nmcli

Verify that all nodes are in the same subnet.

After running the clusterctl install or clusterctl node add commands you cannot change the IP address or hostname of a node.
