已完成的排查操作 #

已关闭防火墙并清空iptables规则，确认端口未被拦截：

$ sudo iptables -nL
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
$ sudo ufw status
Status: inactive

期望服务能正常启动，寻求解决该端口连接被拒问题的方法。
