django和uwsgi只显示特定url的502

我最近把django升级到1.8,芹菜升级到4.1.1。升级后,服务器上只有一个url出现502错误。

我在用 uwsgi .这是一些代码。我遇到的问题是 judging/

urlpatterns = patterns('lbb.views',
    url(r'^judging/', include('judging.urls')),
)

判断应用程序中的url.py

urlpatterns = patterns('judging.views',
    url(r'^$', AppView.as_view(), name='judge_home')
)

景色是

class AppView(TemplateView):
    template_name = 'judging/app.html'

    def get(self, request, *args, **kwargs):
        """ method get of class JudgeLoginView """
        if not request.user.is_authenticated():
            url="%s?next=%s" % (reverse("judge_login"), '/judging/#/judge_home')
            return redirect(url)
        return super(AppView, self).get(self, request, *args, **kwargs)

它通常正常运行。但升级后我遇到了这个问题。nginx文件是

upstream application {
    server lbb-app:8000;
}


server {
    listen 80 default_server;

    charset     utf-8;

    client_max_body_size 4G;   # adjust to taste
    server_tokens off;

    add_header X-Content-Type-Options nosniff;

    add_header X-XSS-Protection "1; mode=block";

    add_header Cache-Control "no-store";

    add_header Pragma "no-cache";

    add_header Strict-Transport-Security "max-age=31536000; includeSubdomains;";


    location /work {
        include     uwsgi_params;
        uwsgi_pass  application;
    }


    location / {
        include     uwsgi_params;
        uwsgi_pass  application;
    }
}

Uwsgu.ini是

[uwsgi]
env=DJANGO_SETTINGS_MODULE=lbb.settings.common
chdir=/opt/webapp
module=lbb.wsgi:application
reload-mercy=10
master=1
no-orphans=1
workers=4
enable-threads=1
single-interpreter=1
socket=:8000
harakiri=20
max-requests=5000
vacuum=1
buffer-size = 65535

我在nginx配置中做了一些更改并部署了几次。但换回旧的重新部署。其他url都可以正常工作。除了我提到的那个 https://website/judging/ 是的。我试着评论一些不必要的代码。但还是不行。
