[Windows]go get github.com/gin-gonic/gin failed with connectex: A connection attempt failed

Question

Code:

package main

import "github.com/gin-gonic/gin"

func main() {
    r := gin.Default()

    r.Handle("GET", "/ping", func(context *gin.Context) {
        context.JSON(200, gin.H{
            "message": "pong",
        })
    })

    r.Run() 
}

Error:

C:\Users\hxia\go\Gin>go run main.go
main.go:3:8: no required module provides package github.com/gin-gonic/gin; to add it:
        go get github.com/gin-gonic/gin

Description:

With the go get to download the Gin module, it shows failed with a connection error, check the env it seems configure right with:

set GO111MODULE=on
set GOPROXY=https://goproxy.cn,direct

Change the GOPROXY to https://goproxy.io.direct it failed too.

I have configured a http_proxy in visual studio, then suspend whether is something wrong with the proxy, so remove the proxy, change the proxy from HTTP to HTTPS, all failed.

could any experts can point the issue out, how can I fix the issue? thanks so much!!
