Retrofit Can't return Data

i'm probebly doing something wrong, i'm trying to figure out how to use retrofit, so for now i'm calling back just a general ResponseBody, and not yet parsing anything, (just a simple http get)

but retrofit can't get the data, what am i doing wrong ? >

my Retrofit API >

public interface retrofitApi {

    String baseUrl = "http://localhost:3003/";

    @GET("api/radBox/getDegrees")
    Call<ResponseBody> getCallData();


    class Factory {
        private static retrofitApi service;

        public static retrofitApi getInstance() {
            if (service == null) {
                Retrofit retrofit = new Retrofit.Builder()
                        .baseUrl(baseUrl)
                        .addConverterFactory(GsonConverterFactory.create())
                        .build();

                service = retrofit.create(retrofitApi.class);
                return service;
            } else {
                return service;
            }

        }
    }


    }

and in my main Activity i put > 

retrofitApi.Factory.getInstance().getCallData().enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {

            Log.d("myLogs", "log: " + response);

        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            Log.d("myLogs", "failed to Retrive Data");


}
        });

I think your problem is caused by using "localhost". Looks like you are using your phone to connect to phone's 3003 port. Exchange the localhost to your Server IP to give a try.

I copy all your code in my retrofit project, I exchange the URL, everything is working well on my side, meaning your retrofit code has no problem.

Try use instead ResponseBody your model (for me it WeatherModel) which must will return from server. Like this

String baseUrl = "http://api.openweathermap.org/";

@GET("data/2.5/weather")
Call<WeatherModel> getCallData(@Query("q") String q, @Query("lang") String lang,
                               @Query("appid") String appid);

and put in MainActivity like this

retrofitApi.Factory.getInstance()
            .getCallData("Taganrog,ru", "ru", "bde41abf61e82b6209a544a5ea2ddb76")
            .enqueue(new Callback<WeatherModel>() {
        @Override
        public void onResponse(Call<WeatherModel> call, Response<WeatherModel> response) {
            Log.d("myLogs", "log: " + response);
        }

        @Override
        public void onFailure(Call<WeatherModel> call, Throwable t) {
            Log.d("myLogs", "log: " + "failed to Retrive Data");
        }
    });

It's works fine for me
