This is a web api method that worked fine in a asp.net 4.x mvc web app for ages but i'm putting it into a asp.net core web app. Its just a GET request and if you browse to it Chrome it appears to bring back all the JSON OK but the request never actually completes, there is a spinner icon on the browser that goes on and on and in developer tools it says status failed "ERR_CONNECTION_RESET"
I can't understand why the API call is acting like this.
