InstagramAuthException: Access denied in getAccountByUsername method

[cemcocu]

Hello,
I added the maven dependency from this link
and here is my simple code :

 HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
        loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient httpClient = new OkHttpClient.Builder()
                .addNetworkInterceptor(loggingInterceptor)
                .addInterceptor(new ErrorInterceptor())
                .cookieJar(new DefaultCookieJar(new CookieHashSet()))
                .build();

                 Instagram i=new Instagram(httpClient);

        Account ac=new Account();
        try {
             ac = i.getAccountByUsername("kevin");
        } catch (IOException e) {
            e.printStackTrace();
        }
             return ac;

I am getting the error : instagram.scraper.exception.InstagramAuthException: Access denied

And this is the output of my instagram object which i named in the code as "i"
