Hello - we would need more info about what is problematic from the Elasticsearch side of things (rather than Kibana).

Therefore, initiate the "start trial" API call (https://www.elastic.co/guide/en/elasticsearch/reference/current/start-trial.html) using either Dev Tools Console or curl. Let us know what the response is to that API call.

Also, watch the elasticsearch.log file for any errors being reported. Post those relevant lines after the API is called here.
