Problem in deploying an Elasticsearch cluster

Elastic Stack Elasticsearch
1

Hi
I tried to deploy an ELasticsearch cluster by first installing 3 master nodes (stacks 7.9)
everything is fine but when I try to connect the nodes to each other some weird situation occurs.
at first all the nodes working fine as single but clustering them by using the configs below and copy "elastic-certificates.p12" and "node.p12" from the first node to the other ones, results in the errors I can't understand why

/etc/elasticsearch/elasticsearch.yml

path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch

path.repo: ["/elasticsearch_backup"]

network.host: ["localnode.net"]
http.port: 9200

xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate

xpack.security.transport.ssl.truststore.password: "password"

xpack.security.http.ssl.enabled: true

xpack.security.http.ssl.truststore.path: node.p12

xpack.security.http.ssl.truststore.password: "password2"

cluster.name: myCluster
node.name: Node1

any suggestions?

Your cluster previously only had a single master node which you've now set to be voting-only. Set it back to being a full master until the cluster has expanded.
