问题
I have issues when trying to Post data to my API using ServiceStack's JsonServiceClient.
I get the following error message in the console
Access to fetch at 'https://192.168.10.191:5001/json/reply/CreateEquipment' from origin 'http://192.168.10.191:5000' has been blocked by CORS policy: Request header field headers is not allowed by Access-Control-Allow-Headers in preflight response.
I have added 192.168.10.191:5000 to the Whitelist.
I can see in the network tab that it tries to access "https://192.168.10.191:5001/json/reply/CreateEquipment" but nothing is showing when I capture the traffic using fiddler.
I have attached an image of the headers. https://i.stack.imgur.com/hUfII.png

Your requesting a https resource at port 5001 but your origin white list returns a http resource on 5000, they need to match.
