(Question) Golang client compatibility

[andvary]

Greetings!
I’m trying to implement a gRPC server based on the examples you have provided.
As for the client, I’m using a Go client, setting it up like this:

func setupClient(target string) (pb.Rpc1Client, error) {
  conn, err := grpc.Dial(target, grpc.WithTransportCredentials(insecure.NewCredentials()))
  if err != nil {
    return nil, err
  }
  return pb.NewRpc1Client(conn), nil
}

Unfortunately, when trying to send a request to the server I get an error. Client side:

2023/08/03 05:37:01 INFO: [transport] transport: loopyWriter.run returning. connection error: desc = "transport is closing"
2023/08/03 05:37:01 WARNING: [core] grpc: addrConn.createTransport failed to connect to {192.168.98.13:7777 192.168.98.13:7777 <nil> <nil> 0 <nil>}: failed to receive server preface within timeout

Server side: PROTOBUF_C_RPC_PROTOCOL_STATUS_INCOMPLETE_BUFFER

Successful request, C client:

Failed exchange, Go client:

It looks like the Go client attempts to connect using HTTP/2 as transport whereas the server does not support it.
Could you please help me solve this problem: is there a way I can tune the server to be compatible with the Go client or it is not possible at all?
