Django网站部署至服务器后CSS无法加载，后台样式异常求助

我已将Django项目部署至服务器（网址：www.sb10-89.co.uk），但CSS文件无法正常加载，甚至后台管理页面样式也显示异常，推测同样是缺少CSS文件导致。

settings.py相关配置 #

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

STATIC_URL = 'staticfiles/bands_ratings'

项目文件结构 #

HTML中CSS引入代码 #

<link rel="stylesheet" href="{% static 'Style.css' %}">

项目根目录urls.py代码 #

from django.contrib import admin
from django.urls import path , include
from django.views.generic import RedirectView
from django.contrib.auth.views import LogoutView


urlpatterns = [
    path("admin/", admin.site.urls),
    path('bands_ratings/', include ('bands_ratings.urls')),
    path('',RedirectView.as_view(url='bands_ratings/signup/')),        
    path('accounts/', include('django.contrib.auth.urls'))
]
#urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
