We have our api hosted at: https://oursitename.com
When we try opening our OpenAPI spec here: https://oursitename.com/openapi/v1/openapi.json, we see that server name specified there is incorrect one: "https://realsitename.azurewebsites.net".
Some additional info: oursitename.com is a CNAME record which points to realsitename.azurewebsites.net. Somehow NSwag shows the latter, even though we access our site through former.
