Why does nginx do a 301 redirect?

Question

Django

Hello, there is such an incomprehensible problem. When I send a backend request with curl like:
curl -X POST -i -H "Content-Type: application/json" -d '{"phone_number":"+.....","password":" 1qaz1qaz"}' server_name/users
Then nginx does a redirect 301 and nothing else. (And the request must create a user and return code 201)
And when the request is like:
curl -X POST -i -H "Content-Type: application/json" -d '{"phone_number":"+....... ","password":"1qaz1qaz"}' server_name/login
Then everything works as it should.
What is the problem?

Answer 1

Well, the backend is likely to redirect.
Here and there without nginx configs and code from the /users route, they will not help you in any way.
