Akka - 远程集群发现

Question

我正在设置一个Akka集群，以便能够使用Artery远程连接到其他节点。我按照以下教程设置了几个本地节点来模拟这种效果（https://developer.lightbend.com/docs/akka-management/current/bootstrap/local-config.html），它的工作原理。这是我的配置文件：

akka {
  loglevel = INFO

  actor {
    provider = "cluster"
  }

  remote {
    artery {
      enabled = on
      transport = tcp
      hostname = "MY_PUBLIC_IP_ADDRESS(130.231.......)"
      canonical.port = 2551
    }
  }


}

#coorindated-shutdown
akka.cluster.shutdown-after-unsuccessful-join-seed-nodes = 30s
akka.coordinated-shutdown.exit-jvm = on
#coorindated-shutdown

#discovery
akka.discovery {
  config.services = {
    local-cluster = {
      endpoints = [
        {
          host = "127.0.0.2"
          port = 8558
        },
        {
          host = "127.0.0.3"
          port = 8558
        }
      ]
    }
  }
}
#discovery

#health
akka.management.health-checks {
  readiness-path = "health/ready"
  liveness-path = "health/alive"
}
#health

akka.management.http {
  route-providers-read-only = false
}

#bootstrap
akka.management {
  cluster.bootstrap {
    contact-point-discovery {
      service-name = "local-cluster"
      discovery-method = config
    }
  }
}
#bootstrap

现在，当我在具有另一个IP地址的另一台机器上启动完全相同的程序实例并且我在akka.discovery.config.services.local-cluster.endpoints中提供该IP地址时，引导程序完全失败（它甚至无法再发现以前工作的127.0.0.2地址） ，给我连接被同行错误消息拒绝。

知道我还缺少什么其他设置才能在完全偏远的情况下工作吗？谢谢 ！

我对此的修复最终是切换到种子节点设置（不再发现）并按以下格式对IP进行硬编码：akka://{CLUSTER_NAME}@{REMOTE_IP}:{PORT}
