Hello and welcome,

You have only one node with the `master` role, the `discovery.seed_hosts` is a list of master eligible nodes, so it needs to haver just the master eligible node, remove the non-eligible nodes from this list.

Did you manually generated the certificates? If true you need to remove this `xpack.security.enrollment.enabled: true` from the configuration file, the enrollment process only works if security is auto-configured.

Also, you have 3 nodes, why use just one as a master? Your cluster will not be resilient to failures.
