Swagger with Gorilla Mux - 404 Page Not Found Error

[AzzamSyakir]

Hello everyone,
I think this might be a simple issue, but I can't figure out what's wrong. I'm trying to integrate Swagger with Gorilla Mux, but whenever I try to access the Swagger UI, I get a "404 Page Not Found" error.

Here's the code I'm using:

package main

import (
	"fmt"
	"log"
	"net/http"

	_ "my-project/api/docs"

	"github.com/gorilla/mux"
	httpSwagger "github.com/swaggo/http-swagger/v2"
)

// @title Swagger Example API
// @version 1.0
// @description test.
// @tag.name test
// @tag.description test
// @tag.docs.url https://example.com
// @tag.docs.description Best example documentation
// @termsOfService http://swagger.io/terms/
// @contact.name Azzam Syakir
// @contact.url https://github.com/AzzamSyakir
// @contact.email azzam.sykir.work@gmail.com
// @host localhost:8080
func main() {
	r := mux.NewRouter()

	r.PathPrefix("/swagger/*").Handler(httpSwagger.Handler(
		httpSwagger.URL("http://localhost:1323/api/docs/doc.json"), //The url pointing to API definition
		httpSwagger.DeepLinking(true),
		httpSwagger.DocExpansion("none"),
		httpSwagger.DomID("swagger-ui"),
	)).Methods(http.MethodGet)
	fmt.Println("start")
	log.Fatal(http.ListenAndServe(":1323", r))
	fmt.Println("finish")
}

I'm trying with the standard net/http package and I can't figure out how to make it work, it only shows 404

I just got it works to the swagger doc page but it said Failed to load API definition.

my config is like this
r.PathPrefix("/swagger").Handler(httpSwagger.Handler(httpSwagger.URL("http://localhost:8080/docs/doc.json"))).Methods("GET")

hope it helps
