The cluster engine used multicast traffic to realize the communicate between both nodes. As we always have a two node setup while knowing both of them, we decided to change the communication to UDP unicast.
This will take effect for all new set-up clusters. Existing clusters will remain using multicast until both nodes are stopped and the configuration is edited using the web configuration. This step will rewrite the configuration to use unicast instead of multicast on both nodes and make the cluster use unicast after starting the nodes again.
