Unable to join ES node with different cluster_uuid

[sc5283 (Servando)]

I am unable to join ES node to a cluster (do not see it kibana monitoring / cluster nodes, and I can connect to the endpoint from all locations to the default port 9200).
The only difference I found between all nodes is the cluster_uuid which is different for that node.

Assuming this is the issue, how do I change the cluster_uuid on that node to be the same as the others?

What do your elasticsearch.yml files look like for the nodes that are connected to the cluster versus the node that wont connect?

The only items configured in elasticsearch.yml:
cluster.name: ES_Cluster
node.name: ${HOSTNAME}
discovery.zen.minimum_master_nodes: 2

if I connect to the port on the nodes: (for es1 and es3),
Note: I changed the uuids...do not know if they need to be secured

{
"name" : "es1",
"cluster_name" : "ES_Cluster",
"cluster_uuid" : "123456789",
"version" : {
"number" : "6.3.0",
"build_flavor" : "default",
"build_type" : "rpm",
"build_hash" : "424e937",
"build_date" : "2018-06-11T23:38:03.357887Z",
"build_snapshot" : false,
"lucene_version" : "7.3.1",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}

for node2 this is the result: (cluster_uuid is different)

{
"name" : "es2",
"cluster_name" : "ES_Cluster",
"cluster_uuid" : "abcdef12345",
"version" : {
"number" : "6.3.0",
"build_flavor" : "default",
"build_type" : "rpm",
"build_hash" : "424e937",
"build_date" : "2018-06-11T23:38:03.357887Z",
"build_snapshot" : false,
"lucene_version" : "7.3.1",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
