I did not upgrade the Kibana or ES to 5.4.0 (they are on 5.2.0), but I am getting the following error:
This version of Kibana requires Elasticsearch v5.4.0 on all nodes. I found the following incompatible nodes in your cluster: v5.2.0 @ 192.168.1.114:9200 (192.168.1.114)
How can this be if I didnt upgrade the Kibana?
does this mean every time Kibana has a new version we need to upgrade the ES?
