I assume it's a network communication problem. Any firewall on your hosts? Is IP multicast supported in your network environment?

Hello,

the hosts themselves have none own firewall installed.
But on the hosts are running VMs with firewalls, but these are in other vlans.
IP multicast is working.

Today we added entries for all nodes in all /etc/hosts. Maybe this was an additional error cause.

Greetings
