[GitHub Discussions](https://github.com/apache/rocketmq-clients/discussions).
   
   - [X] I have searched the [GitHub 
Issues](https://github.com/apache/rocketmq-clients/issues) and [GitHub 
Discussions](https://github.com/apache/rocketmq-clients/discussions)  of this 
repository and believe that this is not a duplicate.
   
   - [X] I have confirmed that this bug belongs to the current repository, not 
other repositories of RocketMQ.
   
   
   ### Programming Language of the Client
   
   C++
   
   ### Runtime Platform Environment
   
   Red Hat Enterprise Linux Server release 7.6 (Maipo)
   
   ### RocketMQ Version of the Client/Server
   
   RocketMQ Broker：5.1.3
   c++ client: RocketMQ gRPC Client Cpp SDK 5.0.0
   
   ### Run or Compiler Version
   
   _No response_
   
   ### Describe the Bug
   
   grpc代理模式下，客户端endpoint填入两个IP：ip1:port1;ip2:port2,broker上proxy.log会报错，如下：

   c++客户端报错如下：

   初步分析如下：
   1、StaticNameServerResolver函数：
   将分号隔开的两个IP和端口解析到了vector列表
   
   2、amingScheme::buildAddress函数：
   将vector列表里的两个IP拼成了逗号","分割的包含两个IP的string
   
   3、rmq::Endpoints ClientImpl::accessPoint()函数： 
   根据分号";"来拆分上面第2步的string，但因为找不到分号，将整体作为一个IP，经过absl::StrSplit + 
absl::MaxSplits(':', 1)
   "ip1:port1,ip2:port2"被处理成了IP:"ip1:port1,ip2",PORT:port2
   
   4、将IP:"ip1:port1,ip2",PORT:port2 作为endpoint填入grpc数据协议：
       auto addr = new rmq::Address();
       addr->set_host(segments[1]);
       addr->set_port(port);
       access_point.mutable_addresses()->AddAllocated(addr);
   
   ### Steps to Reproduce
   
   c++客户端endpoint填入两个IP+端口
   
   ### What Did You Expect to See?
   
   c++客户端endpoint填入多个IP+端口能够正常处理
   
   ### What Did You See Instead?
   
   客户端报错，Broker端也报错
   
   ### Additional Context
   
   _No response_
