Ngrok服务器搭建好,客户端连不上问题?报错

你好：请教博客轮有个问题.
问题描述: 本地是外网地址请求服务器自己搭建的ngrok不通。
环境描述 ：我的服务端在公网服务器上已经搭建好了。
我用本地 配置如下：
server_addr: "***.cn:4443"
trust_host_root_certs: false
cmd命令打开，把这句脚本放上去：ngrok.exe -config ngrok.cfg -subdomain ***.cn 8080(8080端口已经启动)，
报错信息: Tunnel Status reconnecting
我的ngrok公网服务器 ，地址日志如下，无错误。
