Hello, I have ES -8,1 cluster working . The only change I made to the existing nodes in the cluster is : xpack.security.http.ssl: enabled: false Now , I want to add new data node but getting errors here are my steps: 1: Install the new ES node 2: edit the YAML file and change the xpack.security.http.ssl: to false, 3: change the data and log path 4: set the hostname from local to the IP address 5: add the cluster name and port 6: save the YAML file on the existing master, I got the token on the new node , ran the enrollment token command here is the output **ERROR:Skipping security auto configuration because this node is configured to bootstrap or to join a multi-node cluster, which is not supported** I also tried making the same changes above but add the discovery.seed\_hosts and just start ES with doing the token command In the case. ES started but i get an exception on the log "failed to establish trust with server " In addition , I tried not changing anything in the YAML and run the token command but that too did not work Please let me know what I am missing Thanks ---
