That sounds like the urls that you've defined in Django make /admin point to your index view. Check your urls definitions.
Use the URL in your main project's urls.py ( in the same directory where your WSGI.py file exists).
sample code:
from django.contrib import admin
from django.urls import path
urlpatterns = [
path('admin/', admin.site.urls),
]
