Root Cause

Client is calling a gRPC service that the server has not registered. The server may not have the correct .proto compiled, or the service registration is missing.

generic

中文

客户端调用了服务器尚未注册的 gRPC 服务。服务器可能未正确编译 .proto 文件，或缺少服务注册。

Workarounds

  1. 95% success 
    In server main: pb.RegisterGreeterServer(s, &server{})
  2. 90% success 
    protoc --go_out=. --go-grpc_out=. helloworld.proto

Dead Ends

Common approaches that don't work:

  1. 80% fail

    The server binary still contains old generated code, so the service is still unavailable.

  2. 90% fail

    This will only produce a different Unimplemented error, not fix the root cause.
