final DigestAuthenticator authenticator = new DigestAuthenticator(new Credentials(unicomUserName, unicomPassword));

    final Map<String, CachingAuthenticator> authCache = new ConcurrentHashMap<>();
    final OkHttpClient client = new OkHttpClient.Builder()
            .proxy(new Proxy(Proxy.Type.HTTP, new InetSocketAddress(unicomProxyHost, 8143))) //https:8143
            .authenticator(new CachingAuthenticatorDecorator(authenticator, authCache))
            .addInterceptor(new AuthenticationCacheInterceptor(authCache))
            .build();

// String url = "http://www.google.com";
Request request = new Request.Builder()
.url(unicomUrl)
.build();
try (Response response = client.newCall(request).execute()) {

        return response.body().string();
    }

use proxy and digest lead to error:
