I enabled CORS on the asp.net core server, but it still does not want to process requests from my browser, but everything works fine in Postman
Maybe someone has encountered a similar problem and knows its solutions, please help I have been suffering with this problem for 2 days

Answer 1

Redirect is not allowed for a preflight request.

Probably the problem is that you are returning a redirect.
You can first try adding / at the end of the address,
and if it doesn’t help, look at the Network tab and find out where it redirects you and why.
Another option is that you are accessing http, and the service will redirect you to https
