Tentative fix: The solution addressed here

Transport Client - NoNodeAvailableException[None of the configured nodes are available]

Dear All I solved the issue. I used the docker image to run the elastic search. The command on this page: https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html docker run -p 9200:9200 -e "http.host=0.0.0.0" -e "transport.host=127.0.0.1" docker.elastic.co/elasticsearch/elasticsearch:5.4.3 -e "transport.host=127.0.0.1" did not work. I have to change the elasticsearch.yml, uncomment this line: transport.host: 0.0.0.0 So that the transport client can correctly connect t…

where adding transport: 0.0.0.1 to the elasticsearch.yml file. Ours did not have such a line to uncomment and already had lines related to transport, but adding it still worked.

I'll monitor the system and close it if it doesn't act up again.
