started to fail (cannot connect to [[192.168.2.1]:10051]: [4] Interrupted system call)

52340:20221025:160139.474 active check configuration update from [192.168.2.1:10051] started to fail (cannot connect to [[192.168.2.1]:10051]: [4] Interrupted system call)

解决办法：

1、查看tcp端口状态  # telnet 192.168.2.1 10051   

2、网络不通，查看server的10051端口是否启动  # netstat -tunlp |grep 10051

3、查看firewalld策略  # firewalld-cmd --list-port

4、以上都确认无误，检查物理防火墙设备是否开通相关路由或端口。
