Error 'java.io.EOFException' when transferred Android application from WAMP to external server.

[ghost]

Hello,

I have a problem with retrieving data from my server using retrofit2.
While I was running my Android application on local server, data was retrieving properly.
I changed the server to external one, and then the problem occured.

My logCat:

               java.io.EOFException: End of input at line 1 column 1

Retrofit class:

    public void init() {
        OkHttpClient.Builder okHttpClient = new OkHttpClient.Builder();

        HttpLoggingInterceptor debugger =
                new HttpLoggingInterceptor()
                        .setLevel(HttpLoggingInterceptor.Level.BODY);
        okHttpClient
                .addInterceptor(debugger);

        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(Constants.BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .client(okHttpClient.build())
                .build();

        RequestInterface requestInterface = retrofit.create(RequestInterface.class);

        String email = pref.getString(Constants.EMAIL, "");
        System.out.println(email);
        String id_group = pref.getString(Constants.ID_GROUP, "");
        System.out.println(id_group);
        String nazwa = pref.getString(Constants.NAZWA, "");

        Integer id_int_group = Integer.parseInt(id_group);
        Bookmark bookmark = new Bookmark(email, id_int_group, nazwa);

        ServerRequest request2 = new ServerRequest();
        request2.setOperation(Constants.GET_MY_GROUPS);
        request2.setBookmark(bookmark);

        Call<List<Bookmark>> response2 = requestInterface.operation2(request2);

        response2.enqueue(new Callback<List<Bookmark>>() {

            @Override
            public void onResponse(Call<List<Bookmark>> call, retrofit2.Response<List<Bookmark>> response) {

                listOfBookmarks = response.body();
                bookmarkToString();
                simpleAdapter.notifyDataSetChanged(); // refresh listivew
            }

            @Override
            public void onFailure(Call<List<Bookmark>> call, Throwable t) {

                Log.d(Constants.TAG, "Nie zaladowano!", t);

            }
        });
    }

RequestInterface class:

    @POST("/")
    Call<List<Bookmark>> operation2(@Body ServerRequest request2);

Any solutions appreciated. Thanks!

An EOFException comes from the socket and indicates that the connection was terminated before all the data was available. Perhaps your server is timing out. This is not a problem with Retrofit, though.
