Android Java: выполнить дайджест-проверку подлинности с помощью OkHttp и okhttp-digest -> код ошибки 401

Question

Вот код, который я использую, на стороне сервера все в порядке, так как он работает с HttpURLConnection и bare-bones-digest (я больше не использую его, поскольку сервер ограничен 100 соединения и HttpURLConnection обрабатывают повторное использование соединения) Со следующим кодом я всегда получаю сообщение: Несанкционированный код: 401

private static final MediaType JSON = MediaType.get("application/json; charset=utf-8");
private static String m_user; // Set elsewhere
private static String m_password; // Set elsewhere

private static OkHttpClient getUnsafeOkHttpClient() {
    // For test purpose
    try {
        // Create a trust manager that does not validate certificate chains
        final TrustManager[] trustAllCerts = new TrustManager[] {
                new X509TrustManager() {

                    @Override
                    public void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                    }

                    @Override
                    public void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                    }

                    @Override
                    public X509Certificate[] getAcceptedIssuers() {
                        return new X509Certificate[0];
                    }

                    // Called reflectively by X509TrustManagerExtensions.
                    public void checkServerTrusted(X509Certificate[] x509Certificates, String authType, String host) {
                    }
                }
        };

        // Install the all-trusting trust manager
        final SSLContext sslContext = SSLContext.getInstance("SSL");
        sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
        // Create an ssl socket factory with our all-trusting manager
        final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

        OkHttpClient.Builder builder = new OkHttpClient.Builder();
        builder.sslSocketFactory(sslSocketFactory, (X509TrustManager)trustAllCerts[0]);
        builder.hostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        });

        return builder.build();
    } catch (Exception e) {
        e.printStackTrace();
        throw new RuntimeException(e);
    }
}

Функция вызывается с тайм-аутом = 1000, isPost = true, digestAuth = правда, данные json формат:

private void testConnect(int timeout, final String str_url, boolean isPost, boolean digestAuth, String data)
{
    OkHttpClient client = getUnsafeOkHttpClient(); // For test purpose
    OkHttpClient.Builder clientBuilder = client.newBuilder();
    clientBuilder.connectTimeout(timeout, TimeUnit.MILLISECONDS);
    clientBuilder.writeTimeout(timeout, TimeUnit.MILLISECONDS);
    clientBuilder.readTimeout(10, TimeUnit.SECONDS);

    if(digestAuth) {
        final DigestAuthenticator authenticator = new DigestAuthenticator(new Credentials(m_user, m_password));
        final Map<String, CachingAuthenticator> authCache = new ConcurrentHashMap<>();
        clientBuilder.authenticator(new CachingAuthenticatorDecorator(authenticator, authCache));
        clientBuilder.addInterceptor(new AuthenticationCacheInterceptor(authCache));
    }
    clientBuilder.build();

    Request request = new Request.Builder()
            .url(str_url)
            //.header("Accept", "application/json")// todo Add Headers ?
            .build();
    Request.Builder requestBuilder = request.newBuilder();

    if(isPost) {
        RequestBody body = RequestBody.create(data, JSON);
        requestBuilder.post(body);
    }

    requestBuilder.build();

    client.newCall(request).enqueue(new Callback() {
        @Override
        public void onFailure(@NotNull Call call, @NotNull IOException e) {
            Handler handler = new Handler(Looper.getMainLooper());
            handler.post(new Runnable() {
                @Override
                public void run() {
                    Toast.makeText(myClass.this, e.getMessage(), Toast.LENGTH_SHORT).show();
                }
            });
        }

        @Override
        public void onResponse(@NotNull Call call, @NotNull okhttp3.Response response) {
            if (!response.isSuccessful()) {
                Handler handler = new Handler(Looper.getMainLooper());
                handler.post(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(myClass.this, response.message() + " code: " + response.code(), Toast.LENGTH_SHORT).show();
                    }
                });
            } else {
                if(response.code() == HttpURLConnection.HTTP_OK) {
                    Handler handler = new Handler(Looper.getMainLooper());
                    handler.post(new Runnable() {
                        @Override
                        public void run() {
                            Toast.makeText(myClass.this, "OK", Toast.LENGTH_SHORT).show();
                        }
                    });
                }
            }
        }
    });
}

Спасибо, скажите мне, что не так.
