How to allow connection to local angular access to web api, cors policy from browser?

Question

Angular

Can't send request to web api. Both projects are local. I am accessing the web api:

return this.http.post('https://localhost:44375/api/ApplicationUser/Register', body);

configured CORS on the server:

app.UseCors(builder => builder.WithOrigins("http://localhost:4200").AllowAnyHeader().AllowAnyMethod());

I also made settings on the server, based on the Microsoft Documentation . Still the same error
Error:

Access to XMLHttpRequest at 'https://localhost:44375/api/ApplicationUser/Register' from origin 'http://localhost:4200' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

POST https://localhost:44375/api/ApplicationUser/Register net::ERR_FAILED

From Postman everything is fine, requests pass.
