I set my DEBUG variable to False  in setting.py and deployed my project in cpanel,used collectstatic command but static files  not loading.
setting.py
STATIC_URL = '/static/'
MEDIA_URL = '/media/'
if DEBUG:
    STATICFILES_DIRS = [(
            BASE_DIR / 'static/')
    ]
    MEDIA_ROOT = os.path.join(BASE_DIR, "static_cdn", "media_root")
else:
    STATIC_ROOT = "/home/smartsbi/public_html/static"
    MEDIA_ROOT = "/home/smartsbi/public_html/media"
urls.py
urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('home.urls')),
    path('blog/', include('blog.urls')),
    path('ckeditor/', include('ckeditor_uploader.urls')),
    path('', include('contact_us.urls')),
    path('', include('service.urls')),
]
if settings.DEBUG:
    # add root static files
    urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
    # add media static files
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
