okhttp asynchronous post always executing onFailure

Hi! I'm trying to perform an asynchronous post with okhttp. I'm trying to send a string specified by postBody (an email and password) and i'm expecting to get a string in response (an authentication token). When the code is executed, the onFailure method is always executed after a slight delay. Can anyone spot any blatant mistakes?

String url = "https://hoverapp.herokuapp.com/authenticate"; String email = "d1@example.com"; String password = "password";

            = MediaType.parse("text/plain; charset=utf-8");

    OkHttpClient client = new OkHttpClient();

    String postBody = "{\"email\":\""
            + email + "\",\"password\":\""
            + password + "\"}";
    Request request = new Request.Builder()
            .post(RequestBody.create(MEDIA_TYPE_MARKDOWN, postBody))

    Call call = client.newCall(request);
    call.enqueue(new Callback() {
        public void onFailure(Call call, IOException e) {
            Log.d(TAG,"failed in callback");

        public void onResponse(Call call, Response response) throws IOException {
            try {
                //Response response = client.newCall(request).execute();
                mAuthResponse = response.body().string();
                Log.d(TAG,"response.body().string() was received.");
                if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
            catch (IOException e){
