Hi, I tried this 3 times now from scratch. I followed documentation. I have 3 nodes in a LAN, no firewalls.
relevant config lines:
dbms.mode=CORE
# Expected number of Core servers in the cluster at formation
causal_clustering.minimum_core_cluster_size_at_formation=3
# Minimum expected number of Core servers in the cluster at runtime.
causal_clustering.minimum_core_cluster_size_at_runtime=3
# A comma-separated list of the address and port for which to reach all other members of the cluster. It must be>
# host:port format. For each machine in the cluster, the address will usually be the public ip address of that m>
# The port will be the value used in the setting "causal_clustering.discovery_listen_address".
causal_clustering.initial_discovery_members=10.4.0.100:5000,10.4.0.101:5000,10.4.0.102:5000
# Host and port to bind the cluster member discovery management communication.
# This is the setting to add to the collection of address in causal_clustering.initial_core_cluster_members.
# Use 0.0.0.0 to bind to any network interface on the machine. If you want to only use a specific interface
# (such as a private ip address on AWS, for example) then use that ip address instead.
# If you don't know what value to use here, use this machines ip address.
causal_clustering.discovery_listen_address=10.4.0.100:5000
# Network interface and port for the transaction shipping server to listen on.
# Please note that it is also possible to run the backup client against this port so always limit access to it v>
# firewall and configure an ssl policy. If you want to allow for messages to be read from
# any network on this machine, us 0.0.0.0. If you want to constrain communication to a specific network address
# (such as a private ip on AWS, for example) then use that ip address instead.
# If you don't know what value to use here, use this machines ip address.
causal_clustering.transaction_listen_address=10.4.0.100:6000
# Network interface and port for the RAFT server to listen on. If you want to allow for messages to be read from
# any network on this machine, us 0.0.0.0. If you want to constrain communication to a specific network address
# (such as a private ip on AWS, for example) then use that ip address instead.
# If you don't know what value to use here, use this machines ip address.
causal_clustering.raft_listen_address=10.4.0.100:7000
I always end up with the following in logs:

What am I doing wrong here? This should be easy and straight forward
I also tried the unbind thing with neo4j admin but it didn't change anything, shouldnt be required on a fresh install anyway?
Thanks for help
