getting no access control error

[bigerock]

i'm getting a 'no access control allow origin' error (see below) when i've updated this project to use iis instead of iis express using local host headers. meaning, i've switched from using https://localhost:[port] to something like http://myapi.test for my web api and http://myapp.test for my app in iis. i've added the 'EnableCors' attribute on my web api controller, and properly called out http://myapp.test within the attributes - as the example has shown.

does this perhaps need a fully qualified domain in order to run properly?

Error:
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://myapp.test' is therefore not allowed access. The response had HTTP status code 405.

on my controller:
[EnableCors("http://myapp.test", "", "")]

Fully qualified domain name issue is related to the IE browser.
Error is saying that server side is not sending the 'Access-Control-Allow-Origin' header. Browsers check that header for CORS request.

do you have any idea what I might try then?
