Root Cause

Server is not running or the port is not open.

generic

中文

服务器未运行或端口未开放。

Workarounds

  1. 100% success 
    lis, _ := net.Listen("tcp", ":50051"); s := grpc.NewServer(); pb.RegisterGreeterServer(s, &server{}); s.Serve(lis)
  2. 90% success 
    Ensure client dials the correct address: grpc.Dial("localhost:50051", grpc.WithInsecure())

Dead Ends

Common approaches that don't work:

  1. 90% fail

    The server is not listening on any port.

  2. 50% fail

    Firewall is not the issue if the server is not running.
