Please note that 6.5 has been EOL for some time now. You should be using 7.10.1 as the current latest release.

Ok but what about the Kibana logs?

Okay, so I might need to upgrade elasticsearch???
Here are the logs from kibana

Could you point me to any useful link on how to successfully update the elasticsearch?

https://www.elastic.co/guide/en/elastic-stack/7.10/upgrading-elastic-stack.html is the best place for that :slight_smile:
