FAILED - RETRYING: Wait until the etcd cluster is healthy

[LeGrim94]

I keep getting this error (I opened the ports on my aws ec2-machine and modified the whole project with the rights IPs: previous steps are workin' fine. I get stuck here "name: Wait for port 2379 to become open on the host"). What can I do?

To be more specific

Hi @LeGrim94

You have an error at the stage of performing a cluster health check using the command etcdctl cluster-health

connection refused\n member cdbb13876426f862 is unreachable

this indicates possible network problems, port 2379 (for member cdbb13876426f862) is not available.

it will also be useful to look at the etcd log on all nodes of the cluster:
sudo journalctl -u etcd -n 100 -f --output=short-precise
