Quick rundown of what led to my current issue: [Index filled EC2 completely, manually deleted nodes, no longer able to start Elasticsearch](https://discuss.elastic.co/t/index-filled-ec2-completely-manually-deleted-nodes-no-longer-able-to-start-elasticsearch/300221)

After wiping the node (i.e Deleting everything inside the `/var/lib/elasticsearch` folder), Kibana could no longer start as it gives me this error when running `sudo systemctl status kibana`: `[security_exception] failed to authenticate user [kibana]` and `"license information could not be obtained from Elasticsearch for the data cluster"`

I just did a fresh reinstall of Kibana via `dpkg -i kibana..._.deb` and the issue still persists. I suspect that it has to do with the elastic install holding onto some authentication info from the (now deleted) `.kibana` index that no longer exists? Perhaps the keystore is out of date in `/etc/elasticsearch`?

You need to set up again your built-in users passwords with the [`elasticsearch-setup-passwords`](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-passwords.html) command. The command will ask for the passwords for all the [built-in users](https://www.elastic.co/guide/en/elasticsearch/reference/current/built-in-users.html) `elastic`, `kibana_system`, etc

Perfect! I forgot the passwords so I followed this guide to reset it: [I lost the password that has been changed - #2 by TimV](https://discuss.elastic.co/t/i-lost-the-password-that-has-been-changed/91867/2)
