I have upgraded ES/Kibana/Logstash from v7.62. to v7.15.2.  
All installations are success but KIBANA services started with error.

Can someone help me with the below error? I have no idea how to resolved it.

Kibana log  
`{"type":"log","@timestamp":"2021-12-07T16:42:21+08:00","tags":["error","savedobjects-service"],"pid":2031,"message":"Unable to retrieve version information from Elasticsearch nodes. security_exception: [security_exception] Reason: missing authentication credentials for REST request [/_nodes?filter_path=nodes.*.version%2Cnodes.*.http.publish_address%2Cnodes.*.ip]"}`

Thanks for replying. ES cluster is working now. But Kibana is not working.....the web show "server is not ready yet".

You should ask this question in the Elasticsearch section as it looks like there may be a problem with your cluster and not with logstash.

What is the output from calling `ELKNode:9200/`?

When I upgraded ES successfully, it is output below message.

You should try to restart Kibana then. If it's not working please post the log from when the process starts to whatever the latest entry is.

Take a look at [Configure Kibana | Kibana Guide [8.11] | Elastic](https://www.elastic.co/guide/en/kibana/current/settings.html)

Specifically - `elasticsearch.username:` and `elasticsearch.password:`
