I'm trying to set up my first cluster in AWS. I have 3 EC2 instances. Following the manual and it appears as if the cluster is established, but when I try to cypher-shell
from one of the instances I get a Connection Refused
. Any tips where to go about looking to try and figure out how to get this cluster going? I'll paste some what I've found that I think could be relevant. Some AWS setup notes:

I don't know why the 3rd node is waiting to hear from the leader?

I guess the advertised address settings are missing. Amend to your neo4j.conf
file:
dbms.connectors.default_advertised_address=<internal_ip_address_of_this_host>
Note: if your clients (e.g. neo4j browser) are sitting outside on the public interface you might add as well:
dbms.connector.bolt.advertised_address=<external_ip_of_this_host>
dbms.connector.http.advertised_address=<external_ip_of_this_host>
dbms.connector.https.advertised_address=<external_ip_of_this_host>
