Getting java.net.UnknownHostException: in retrofit

When I try to access a URL with getting method getting,

D/OkHttp: <-- HTTP FAILED: java.net.UnknownHostException: Unable to resolve host "xyz.aaa.net": No address associated with hostname 

But I am getting success response in POST MAN. Its been two days but not getting any clue.Changed the Actual URL to xyz.aaa.net due to autorization issue.Sorry for that :

Call<Response> call2 = apiInterface.getEmployeeListNew("1190",1008,"true"
                );
        call2.enqueue(new Callback<Response>() {
            @Override
            public void onResponse(Call<TaxProResponse> call, Response<Response> response) { }

            @Override
            public void onFailure(Call<TaxProResponse> call, Throwable t) {
                call.cancel();
            }
        });

API Client :

class APIClient {

    private static Retrofit retrofit = null;

    static Retrofit getClient() {

        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();


        retrofit = new Retrofit.Builder()
                .baseUrl("http://xyz.aaa.net/api/")
                .addConverterFactory(GsonConverterFactory.create())
                .client(client)
                .build();



        return retrofit;
    }

}

APIInterface :

@GET("Profile")
Call<Response> getEmployeeListNew(
        @Header("app_id") String app_id,
        @Query("office_id") int office_id,
        @Query("need_only_active") String need_only_active
);

whole URL need to be like this with app_id as Header :

http://xyz.aaa.net/api/Profile?office_id=1008&need_only_active=true

If Any of you has faced this issue before please give some suggetion. Tried with some other request,It working fine.Provide the permission,

 <uses-permission android:name="android.permission.INTERNET"/>

Its not issue of permission like other questions in Stackoverflow.Tried with there solutions and its not working.
