SSL/TLS request received but SSL/TLS is not enabled on this node

[2021-02-22T16:37:09,916][WARN ][o.e.t.TcpTransport ] [ip-someip] SSL/TLS request received but SSL/TLS is not enabled on this node, got (16,3,3,1), [Netty4TcpChannel{localAddress=/127.0.0.1:9301, remoteAddress=/127.0.0.1:58934}], closing connection

I have removed the opendistro_security folder to disable security. However, when I try to start ES, i keep getting the above error messages. Not sure why is that happening? I have also commented all the security lines from elasticsearch.yml.

Have you set

opendistro_security.disabled: true

in your elasticsearch.yml as described in Disable Security - Open Distro for Elasticsearch Documentation ?

Nevermind, I am using it with security enabled for now. Works fine.
