Hello @axvfvv79zcx57xv7k

Please review below post where similar issue reported during upgrade :

> [@Issues with upgrade from 8.18.1 to 9.0.1](https://discuss.elastic.co/t/issues-with-upgrade-from-8-18-1-to-9-0-1/378753/7):
>
> I don't know why I'm receiving below error (from dev-tools with elastic account): I think that you are probably hitting elasticsearch (usually port 9200) from dev tools, and that is a kibana (usually port 5601) API. Elasticsearch doesn't know anything about it.

Thanks!!
