whether leak ]?

[wxjin]

No, I think it is splitted by the first ":" and get the ip address

[KomachiSion]

Can you help community to find out the reason? Why the address be split? If gRPC split the address, maybe gRPC's bug, we should upgrade the version.

[KomachiSion]

I found the problem, will be fixed in 2.1.2 version.

[wxjin]

Can you tell me the plan when the 2.1.2 release

[KomachiSion]

Probably this month

[wxjin]

if release, please tell me and we need to do it. thanks

[KomachiSion]

You can watch the release event in github.

[wxjin]

2.1.2 releases， however， why it is not found in mvnrepository?

如果使用ipv6搭建集群的话。1.修改application.properties配置文件，放开nacos.inetutils.ip-address配置项注释，指定本节点nacos节点ip为ipv6地址。2.修改 cluster.conf配置文件使用ipv6地址
以上ipv6地址都需要以‘[]’括住。
