我已遵循本教程：https ://linode.com/docs/databases/postgresql/create-a-highly-available-postgresql-cluster-using-patroni-and-haproxy/ ，以设置高可用性 PostgreSQL 集群使用 Patroni 和 HAProxy。
但是当我尝试启动赞助人时，我收到了这个错误：
ubuntu@sudo patroni /etc/patroni.yml

当然，我在 privateIPoffirstnode、privateIPofsecondnode 等中有真实的 ip。
那么，有谁知道这个错误是什么意思？
