I do not redirect routes

Do this controller in laravel:

    <?php

        }

        $this->usersRepository->delete($id);

        return redirect(route('users.index'));
    }

    //Bloquea la session
    public function lock(){
        $token = Auth::user()->lockToken;
        $locked = Cache::remember('session_lock', 1000, function(){
            return [];
        });
        if(array_key_exists($token, $locked) === false){
            $locked[$token] = back()->getTargetUrl();
        }
        Cache::forever('session_lock', $locked);

        return redirect()->route('locked');
    }

    //Muestra la página de bloqueo
    public function locked(Request $request){
        //Solo puede acceder a esta página se se blokea primero
        if(!LockSession::isLocked()){
            return back();
        }
        return view('users.bloqueo');
    }

    //Verifica si puede desbloquear la sesion con los datos pasados por el request

    public function locked_check(Request $request){

        $email = Auth::user()->name;

        if(LockSession::isLocked() && Auth::attempt([
                'name' => $email,
                'password' => $request->get('password')
            ]))
        {
            $to = LockSession::unlock();

            return redirect($to);

        } elseif(LockSession::isLocked()){

            return redirect()->route('locked')->with('errors', collect(['password' => 'Sus credenciales son incorrectas']));

        }
        return redirect()->route('locked');
    }


}

These are my routes associated with the problem:

Route::post('/bloquea', 'UsersController@lock')->name('auth_lock');

    Route::get('/bloqueado', 'UsersController@locked')->name('locked');

    Route::post('/chaquear_bloquedo', 'UsersController@locked_check')->name('locked_check');

But the function when it reaches the point of redirection: return redirect()->route('locked'); the browser throws me this error:

Esta página no funciona
La página localhost te ha redirigido demasiadas veces.
Borrar las cookies.
ERR_TOO_MANY_REDIRECTS

Has this problem happened to you? How could they solve it?
