Answer 1

From the wiki:

The 404 or Not Found error message is a HTTP standard response code indicating that the client was able to communicate with the server, but the server could not find what was requested. so, your code is OK, but server cannot find resource you are looking for. Double check if your url is correct.

You need to check if you're entering the correct url for the post request.

Answer 2

I have th same problem, but aftrer verifying the url the problem resists. It works with postman.
