The Kibana server logs should provide more information on the version conflicts if any. Plz check that . By default, Kibana logs to `stdout` . You can take a look at the [configuration settings](https://www.elastic.co/guide/en/kibana/current/settings.html) to see how you can change this to log to a file. Pleas see [this version compatibility chart](https://github.com/elastic/kibana#version-compatibility-with-elasticsearch) for more information on how the Kibana and Elasticsearch version numbers interact.
