router does not work when I load the website on the server but if it works on my computer what is the problem?

It's seems you added some Session stuff, like Auth. And on your home site you logged-in and all is ok. One a remote server you have a loop on redirecting when checking Auth or Acl

in sub folder admin on ControllerBase.php file

namespace Project\Controllers\Admin;

use Phalcon\Mvc\Controller;
use Phalcon\Mvc\Dispatcher;
use Project\Auth;
class ControllerBase extends Controller
{

    public function beforeExecuteRoute(Dispatcher $dispatcher)
    {
        $this->view->setMainView('layouts/admin');
        $identity = $this->auth->getIdentity();

        $identity = $this->auth->getIdentity();
        // If there is no identity available the user is redirected to index/index
        if (!is_array($identity)) {
            $this->flash->notice('You don\'t have access to this module: private');
            $this->response->redirect("session/login");
            return false;
        }

    }

    public function afterExecuteRoute()
    {
        $this->view->setViewsDir($this->view->getViewsDir() . 'admin/');
    }

}

I think here I have to make a change, or perhaps in the database table delete sessions_login use the application vokuro

Please give a code of session\login method, it seems like your Session controller extends from ControllerBase

this is the code public function loginAction() { $form = new LoginForm();

    try {

        if (!$this->request->isPost()) {

            if ($this->auth->hasRememberMe()) {
                return $this->auth->loginWithRememberMe();
            }
        } else {

            if ($form->isValid($this->request->getPost()) == false) {
                foreach ($form->getMessages() as $message) {
                    $this->flash->error($message);
                }
            } else {

                $this->auth->check(array(
                    'email' => $this->request->getPost('email'),
                    'password' => $this->request->getPost('password'),
                    'remember' => $this->request->getPost('remember')
                ));

                return $this->response->redirect('admin/index');
            }
        }
    } catch (AuthException $e) {
        $this->flash->error($e->getMessage());
    }

    $this->view->form = $form;
}

Is your Session controller extends from ControllerBase ?

The session controller is extended ControllerBase.php of the root.

Driver runs from ControllerBase.php session of the root within controllers I have a folder called "admin" and inside I have the ControllerBase.php where is the validation to enter the / admin, on my route this specified.

Need a code-review to solve a problem.

Try to look something like dispatcher->forward, it seems you have a cycled dispatcher-forward calls

The problem is that the router does not recognize the namespace

$router->add('/admin/index', array( 'namespace' => 'Avinka\Controllers\Admin', 'controller' => 'index' ));

and it did not work.
