I have a cluster with 3 Elasticsearch nodes and 2 Kibana instances (server 1: elasticsearch + kibana; server 2: elasticsearch + kibana; server3: elasticsearch). I upgraded the cluster from 6.7 to 7.0 and lost the Kibana instance on server 2. I believe the Kibana runs well on the server 2 because netstate shows the port is listening , systemctl status also shows active (running), but stack cluster monitoring only shows 1 instance, e.g. server1. Any idea?

Did you also upgrade Kibana to 7.0? Kibana must be on the same major version as Elasticsearch. [https://www.elastic.co/guide/en/kibana/current/setup.html#elasticsearch-version](https://www.elastic.co/guide/en/kibana/current/setup.html#elasticsearch-version)

Hi Nick, both Kibana and Elasticsearch are version 7.0.0 release 1. I installed kibana on the third server and it also shows Kibana server is not ready yet

Then I would start by checking the log files in `/var/log/kibana/` for the failing Kibana server. You can paste a snippet of the logs here if you need help.
