本地Kubernetes集群中Chainlink节点连接被拒问题求助

本地运行Kubernetes集群，已部署ArgoCD、PostgreSQL和Chainlink应用，所有部署无报错，但无法访问Chainlink节点UI（http://localhost:6688）。复现问题的仓库为chainlink-node。

端口转发异常执行结果 #

执行端口转发命令时出现以下错误：

Forwarding from 127.0.0.1:6688 -> 6688

Pod内执行Chainlink命令异常 #

进入Chainlink Pod执行命令时同样报错：

chainlink@chainlink-8ff64f5c9-gqx6d:~$ chainlink chains evm list
Get "http://localhost:6688/v2/chains/evm": dial tcp [::1]:6688: connect: connection refused

Pod内进程状态 #

但Chainlink节点进程处于运行状态：

chainlink@chainlink-8ff64f5c9-gqx6d:~$ ps aux
