问端口链接拒绝？

nacos单机服务， 默认端口8848，修改端口 18848， 防火墙无论开启&关闭均无法访问，求大佬支援

防火墙添加端口；

firewall-cmd --zone=public --add-port=18848/tcp --permanent

测试端口可用

[root@localhost ~]# sudo firewall-cmd --query-port=18848/tcp

yes

[root@localhost ~]#

nc -lp 18848 & 可以监控到链接信息

[root@localhost ~]# Ncat: bind to :::18848: Address already in use. QUITTING.
