HYBG-1126 opened a new issue, #7362:
URL: https://github.com/apache/inlong/issues/7362
### What happened
安装环境不能链接网络，经过调整，大部分的服务在k8s集群成功运行，但是dashboard始终不成功，出现以下报错；
2023/02/09 11:01:55 [emerg] 7#7: socket() [::]:80 failed (97: Address
family not supported by protocol)
nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by
protocol)
做过的努力：
1、修改nginx的default.conf配置，注释ipv6的80端口监听；
2、增加以下配置到/etc/sysctl.conf中
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1
net.ipv6.conf.eth1.disable_ipv6 = 1
net.ipv6.conf.eth2.disable_ipv6 = 1
net.ipv6.conf.eth3.disable_ipv6 = 1
### What you expected to happen
猜测问题原因是k8s集群没有开启ipv6导致
### How to reproduce
我不认为这个问题可以简单重现
### Environment
inlong version：1.5.0
