Hi , Recently I upgraded elastic, logstash and kibana to 6.4.0 from 6.2.x. After restarting es nodes and tribe, getting below exception. Due to which sync is not happening resulting to stopping indexing. I disabled xpack.security.enabled : false in all nodes. Before installing 6.4.0 i deleted old elasticsearch.keystore and new one got generated automatically while starting up the server. Please someone help here what security/authentication configurations are required.

I got the solution for this. Thanks. Here is what i did: In tribe node , earlier I kept only xpack.security.enabled, but I need to give two settings like below. I don't know the reason, if not given both settings, then again getting exception as xpack.security.enabled is madatory. `tribe.t1.xpack.security.enabled: false` `xpack.security.enabled: false` ---
