I'm trying to follow this blog [https://www.elastic.co/blog/getting-started-with-elasticsearch-security](https://www.elastic.co/blog/getting-started-with-elasticsearch-security) using the version 7.3.1 but i stumble after running this command
$ bin/elasticsearch

Hi Alex,
I already figure it out. Yes im using fresh install. I did is instead of using the command
$ bin/elasticsearch-certutil cert -out config/elastic-certificates.p12 -pass ""
I just use the $ bin/elasticsearch-certutil cert
