Страница не найдена ошибка 404 django navbar link

У меня проблема со ссылкой на navbar, когда она находит html-страницу

my mysite/urls.py

"""firt_website URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/3.2/topics/http/urls/
Examples:
Function views

Class-based views

    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path, include
from pages import urls

app_name = 'pages'

urlpatterns = [
    path('', include('pages.urls')),


]

my blog/urls.py :

from django.contrib import admin
from django.urls import path, re_path
from . import views

app_name = 'main'
urlpatterns = [
    path('', views.home_page, name='homepage'),
    path('education/', views.education, name='education'),
    path('experience/', views.experience, name='experience'),
    path('portfolio/', views.portfolio, name='portfolio'),
]

my navbar.html :

      <div class="u-custom-menu u-nav-container-collapse">
            <div class="u-align-center u-black u-container-style u-inner-container-layout u-opacity u-opacity-95 u-sidenav">
              <div class="u-sidenav-overflow">

</li></ul>
              </div>
            </div>
            <div class="u-black u-menu-overlay u-opacity u-opacity-70"></div>
          </div>

мои взгляды :

from django.shortcuts import render, redirect
from django.core.mail import send_mail, BadHeaderError
from django.http import HttpResponse, HttpResponseRedirect
from django.conf import settings
from .forms import ContactForm

# Create your views here.


def home_page(request):
    return render(request, 'index.html')


def education(request):
    return render(request, 'Education.html')


def experience(request):
    return render(request, 'Experience.html')


def portfolio(request):
    return render(request, 'Portfolio.html')

Борьба у меня возникает, когда я нажимаю на ссылку, то появляется ошибка, что не удается найти страницу или загрузить HTML страницу.

найдите пример этого ниже на изображении :

Знаете, почему, даже если я поставил "/" в blog/urls.py для каждого пути ....?

href="{% url 'experience' %}"
href="{% url 'education' %}"
href="{% url 'portfolio' %}"
href="{% url 'homepage' %}"

from django.contrib import admin
from django.urls import path, include
from pages import urls

urlpatterns = [ 
    path('blog/', include('blog.urls')),
]
