Kibana server is not ready yet issue after upgrade to 6.5.0

Since last night I experience the error message "Kibana server is not ready yet" in the browser when I want to open Kibana. I have upgrade kibana and Elasticsearch to V 6.5.0 .
I've done a lot of research, but I can't find the reason.

@Nuwan, Can you please check the kibana server configuration in kibana.yml file?

Have you defined the elasticserach node IP in elasticserach.uri under kibana.yml file?

One more reason can be have you upgraded your all elasticsearch node on version 6.5.0 as well as kibana also on 6.5.0? If any one of them are still on the older version then there might be compatibility issue. So please check it also.

Thank you very much . your guidance and following link helped to solve that issue



FYI with this kind of logs and on my side it was an index issue on .kibana.
Simple way to fix it is to adapt the kibana's index in the kibana.yml file (and back to the original value after have getting back the hand on the GUI.
kibana.index: ".newkibana"


Thank you .Issue was fix after removing kibana related index and restart the kibana service

check for elasticsearch version, if it is not same version as kibana. please update.
I had the same issue, I have upgraded the elasticsearch to 6.5. then after restarting the services. the issue sorted out.

Good Day..
