Swagger behind Nginx Proxy and CORS error

Hey Newbie1 ,

It's a little out of scope of Swagger UI, how you configure the server for CORS. All browser clients should behave in a similar fashion. 

That said, you should be able to get far debugging the exact error messages that appear in the console. And using https://www.test-cors.org/ to help debug issues.

Console errors can look like his:

You'll note that https://example.com doesn't have a `Access-Control-Allow-Origin` header, in your case you may notice other errors.

Here is an nginx example: https://enable-cors.org/server_nginx.html

Assuming you want full access to the API via the browser, you'd need to use:

- Access-Control-Allow-Origin: <the exact host name> (wildcard * has limitations on Authorization). This is something you're doing though.

- Access-Control-Allow-Headers: GET,POST,PUT,etc

And you'll also need to accept OPTIONS request for preflight requests (the browser asks the server before making the actual request)

Hope that helps!
