rpc错误：代码=不可用 描述=连接错误：描述="传输：拨号时出错：拨号tcp 10.0.0.1:8080：连接被对端重置"

解决方案

1. 85% 成功率 Implement retry with exponential backoff and jitter.

   for i := 0; i < 5; i++ {
       conn, err := grpc.Dial("10.0.0.1:8080", grpc.WithInsecure(), grpc.WithBlock())
       if err == nil { return conn }
       time.Sleep(time.Duration(100*(1<<i)) * time.Millisecond)
   }

2. 90% 成功率 Check server logs and network connectivity.

   Verify server is running: netstat -an | grep 8080. Check firewall rules and network paths.
