[solved] After updating to version 2.2 my second node isn't added to cluster

only one node appears in Elastic HQ.

The configuration of both nodes is equal execpt node.name and network.host.

What may be the reason therefore?

TIA

Ok ... done.
Missing Multicast.

Added
discovery.zen.ping.unicast.hosts : [ otherip ]

on every single host and everything works well.

Thx.
