Retrofit okhttp getting random eofexception

Question

I'm woking on an Android app which is calling a REST WS. The service itself works fine (tested with Postman) but I keep getting occasionally this exception from Android:

: java.io.IOException: unexpected end of stream on com.squareup.okhttp.Address@2cd22e9d

I've find something online about a bug, but I'm not sure. Also, the strange thing is that sometimes works and sometimes don't, without me changing anything in the code. The exception says something about a missing end line character. Do I have to put it in the URL? Here's some code. Thank you.

Api interface

public interface ApiInterface {

@Headers({"Authorization: Bearer eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJkb25hdG8iLCJ1c2VySWQiOiIxIiwicm9sZSI6IlJPTEVfQURNSU4ifQ.yNVtQMfMasfR7nfBgtjtmlXMM8Gpfjvf_FDz1sMiaSJxUvLDyC9sjm-XSEkJdfGy4JasfweRrRUGc3gHpMRA",
            "Accept: application/json",
"Content-Type: application/json;charset=utf-8"})
@POST("/todo/getTodoList")
public void getTodoList(@Body BaseRequest request, Callback<GetTodoListResponse> response);
}

Controller

 RestAdapter restAdapter = new RestAdapter.Builder()
            .setEndpoint("http://www.myUrl.com/app/rest").setLogLevel(RestAdapter.LogLevel.FULL).setConverter(new GsonConverter(builder.create()))
            .setClient(new OkClient(new OkHttpClient()))
            .build();
    ApiInterface methods = restAdapter.create(ApiInterface.class);
    Callback<GetTodoListResponse> callback = new Callback<GetTodoListResponse>() {
        @Override
        public void success(GetTodoListResponse o, Response response) {
            todoList = o.getTodoList();
            Log.d("CardController", "TodoList: " + todoList);
            if (!o.isOutcome()) {
                Log.e("CardController", "Error fetching todoList");
                todoList = new ArrayList<Todo>();
            } else {
                setChanged();
             myMethod();
            }
        }

        @Override
        public void failure(RetrofitError retrofitError) {
            Log.e("Retrofit", "Error fetching todoList: ", retrofitError);
        }
    };
    methods.getTodoList(new AuraBaseRequest(), callback);

It looks to be same as of http://stackoverflow.com/questions/24806797/bug-retrofit-retrofiterror-java-io-eofexception-for-android — Gaurav, Jul 11 '16 at 22:51
@Gaurav thank you for the comment but, as you can see, in my code I'm already using the OkClient as stated in that answer and I get the problem anyway. The thing I don't get is why this error is inconsistent... I'm still looking for a solution after 2 months... — Aurasphere, Jul 23 '16 at 17:25
@Aurasphere Were you able to solve this problem? i'm stuck on this issue from 2 days — rathodbhavikk, Jun 27 '18 at 13:29
@BhavikRathod good luck, I've been stuck on this issue for 2 years and still I have no clue on how to solve it :( — Aurasphere, Jun 27 '18 at 14:23
@Aurasphere So this is the only solution, i have to retry API call if i receive this issue. and one more thing to confirm that are you using more than one Retrofit Library with different version in single project — rathodbhavikk, Jun 27 '18 at 14:30
@BhavikRathod I'm sorry I can't confirm that because I don't work anymore on this project and I honestly can't remember for sure but I don't think I had more than one version of it. — Aurasphere, Jun 27 '18 at 15:01

In my case, the server side was Spring MVC, and I was getting this error. This error happened due to some security check (500 return status), but error in retrofit was unexpected end of stream. Once the security check was bypassed, I was able to get the response.

Hope it might help someone in future.

how did you `bypass the security check`? – likejudo Sep 09 '19 at 17:35
@likejudo : I don't remember it now, but I think it has something to do with spring-security.xml – Monster Brain Sep 11 '19 at 06:11
