Setup Sentry in Django

I installed Sentry through docker-compose, configured it in Django according to the instructions: https://docs.sentry.io/clients/python/integrations/django/ , the corresponding sentry keys generated, everything worked before, this time the sentry errors do not come, began to test:

python manage.py raven test 

got this result:

What could be the reason?

PS: I did not find the reason, in the end I switched to the cloud service sentry.io
