Iyzico payment. Return page error. 404

[cengkaplan33]

Hi peope , I finished Iyzico payment system to .netcore serenity. After payment operation bank must return my fail or success url.
After 3d payment end , bank return my url which is "http://127.0.0.1:5000/PosPaymentThreeDPost".
When Iyzico(bank) return my address it take "404 error"
But I can call my addres from another application or entering chrome browser. and it works.

Can anyone give me a solution or idea about this situation.

My code is like below.
[Route("PosPayment/[action]")]
public class PosPaymentController : Controller
{
[HttpPost,HttpGet]
[Route("~/PosPaymentThreeDPost")]
public ActionResult PosPaymentThreeDPost()
{
return View(MVC.Views.Site.PosPayment.PosPaymentPost,new PosPaymentPostModel(){});
}
}

error :

you wrote the wrong URL for return. Check your URL for the 127.0.0.1:5000;/Pos section has a semicolon, and also it doesn't relate to the serenity platform.
