Your Elasticsearch cluster is Red.

It should be Green (or at least Yellow) to proceed.

Probably need to set your replicas to "0" or check the unassigned indices.

Set replicas to 0

curl -XPUT 'http://<IP Address>:9200/_all/_settings?preserve_existing=true' -H 'Content-Type: application/json' -u user:password -d '{
  "index.number_of_replicas" : "0",
  "index.number_of_shards" : "1"
}'
