Swagger UI unable to show proper response from ASP.net Core WebAPI

Question

I am working with ASP.net Core WebAPI and to produced API documentation I am using Swagger. Swagger successfully generate colourful documentation. But when I try to execute an api method. Always got bellow error from Swagger.

{ "error": "no response from server" }

Api Method

[Route("api/[controller]")]
[Produces("application/json")]
public sealed class AuthController : BaseApiController
{
   [HttpGet]
   [Route("GetByUser/{uid}/{pwd}")]
   public IActionResult GetByUser(string uid, string pwd){....}
 }

Note:

I always got correct api response from above method via Browser / Fiddler (without using Swagger)
I also configure CORS in api end. But from Swagger still not getting proper response.

Swagger AppSettings

 "Swagger": {
    "FileName": "ApiDoument.xml",
    "host": "localhost:63687"

  }

Swagger Response

Curl

X GET 'http://localhost:63687/api/Auth/GetByUser/test%40gmail.com/1234'

Request URL

http://localhost:63687/api/Auth/GetByUser/test%40gmail.com/1234

Response Body

no content

Response Code

0

Response Headers

{ "error": "no response from server" }

I don't know anything about how to fix your issue, but in your Swagger AppSettings there's a typo; FileName: ApiDoument, should be ApiDoCument - Maybe that's it? — cwap, Aug 08 '17 at 13:48
@cwap: FileName don't be an issue here, because Swagger able to generate proper documentation from that "xml" file — Shubhajyoti Ghosh, Aug 08 '17 at 13:53
You need to enable CORS on your localhost. See [Why is there “no response from server” in Swagger UI?](https://stackoverflow.com/q/45439845/113116) — Helen, Aug 08 '17 at 14:05
@Helen I already enable CORS [How to enable CORS in ASP.net Core WebAPI](https://stackoverflow.com/questions/44379560/how-to-enable-cors-in-asp-net-core-webapi) — Shubhajyoti Ghosh, Aug 08 '17 at 14:38
@ShubhajyotiGhosh can you publish your project (or a sample reproducing your issue) to GitHub and post a link here? — Helder Sepulveda, Aug 09 '17 at 01:23
