请求报错No route to host (Host unreachable); nested exception is java.net.NoRouteToHostException: No route to host (Host unreachable)

报错原因

请求对方机器的端口没有打开，访问的目标地址路由不可达，这个no route to host的报错是由于收到icmp路由不可达报文而导致的。
如果是linux，是iptables阻挡造成的，可以用service iptables stop关闭iptables试试

或者开通防火墙对应的端口

查询防火墙是否开启28083端口

sudo firewall-cmd --zone=public --query-port=28083/tcp

防火墙开启28083端口

sudo firewall-cmd --zone=public --add-port=28083/tcp --permanent

防火墙重新加载才能生效

sudo systemctl restart firewalld
或者命令
firewall-cmd --reload

查看防火墙已经开放的端口

sudo firewall-cmd --list-ports
