Hi, > [@shiv94](#): > > for now, there is no ssl set up. can't use x-pack security without using transport ssl in production mode? No. As clearly mentioned in the bootstrap check that failed > [@shiv94](#): > > [1]: Transport SSL must be enabled for setups with production licenses. Please set [xpack.security.transport.ssl.enabled] to [true] or disable security by setting [xpack.security.enabled] to [false] and in our [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks-xpack.html#_ssl_tls_check), TLS on the transport layer is required (unless using a single node listening on loopback ) ---
