根因分析

gRPC服务器反射已启用，但由于网络分区或服务器崩溃，服务器无法访问。

English

gRPC server reflection is enabled but the server is not reachable due to network partition or server crash.

generic

解决方案

  1. 90% 成功率 Check server health endpoint and restart if needed. 
    grpcurl -plaintext localhost:50051 list
  2. 85% 成功率 Verify firewall rules allow gRPC traffic on the target port. 
    nc -zv server-address 50051

无效尝试

常见但无效的做法:

  1. Increase client timeout to 10 seconds. 95% 失败

    The server is not responding at all, timeout won't help.

  2. Add retry logic with exponential backoff. 90% 失败

    Retries won't fix a dead server.
