Retrofit not working on specific versions of android

Question

I have a problem with Retrofit on my emulator running Android 4.3 and my device is on Android 4.4.2 while the same code runs normally on another emulator with Android 7.1.1

Each time I try to execute the get request I get a timeout exception.

java.net.SocketTimeoutException: failed to connect to jsonplaceholder.typicode.com/2606:4700:30::681c:3f5 (port 443) after 10000ms

The code is below

public interface Api {
    String BASE_URL = "https://jsonplaceholder.typicode.com/";

    @GET("posts")
    Call<ArrayList<Post>> getPosts();
}

and the call to the api

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(Api.BASE_URL)
        .addConverterFactory(GsonConverterFactory.create())
        .build();

Api api = retrofit.create(Api.class);
Call<ArrayList<Post>> call = api.getPostes();
Log.i("RequestUrl", call.request().url().toString());
call.enqueue(new Callback<ArrayList<Post>>() {
    @Override
    public void onResponse(Call<ArrayList<Post>> call, Response<ArrayList<Post>> response) {
        mPostsList.setValue(response.body());
    }

    @Override
    public void onFailure(Call<ArrayList<Post>> call, Throwable t) {
        Log.e("Posts", "Error occurred", t);
    }
});

Android prior to 21 has some missing SSL and Retrofit wont work. Using google services you can update the device protocols after that the HTTP request will work

    //compile 'com.google.android.gms:play-services-base:11.0.0'
     //remember to add the library in your dependencies

        //compile 'com.google.android.gms:play-services-base:$currentVersion'

        ProviderInstaller.installIfNeededAsync(this, new ProviderInstallListener() {

            @Override

            public void onProviderInstalled() {

                //Do your http request here

            }


            @Override

            public void onProviderInstallFailed(int errorCode, Intent recoveryIntent) {

                //sad face :C is sad

            }

        });
