Why I can not get the response "pong" while I run the example1?

[mumingv]

main.go:

package main

import (
    "log"
    "net/http"

    "github.com/gin-gonic/autotls"
    "github.com/gin-gonic/gin"
)

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

    // Ping handler
    r.GET("/ping", func(c *gin.Context) {
        c.String(http.StatusOK, "pong")
    })

    log.Fatal(autotls.Run(r, "example1.com", "example2.com"))
}

After running the main.go，I typed https://localhost:443/ping in browser, I just get "ERR_SSL_PROTOCOL_ERROR" wrong message.

And the console shows the error messages as below:

2023/01/22 17:58:05 http: TLS handshake error from [::1]:51238: acme/autocert: server name component count invalid
2023/01/22 17:58:05 http: TLS handshake error from [::1]:51239: acme/autocert: server name component count invalid
2023/01/22 17:58:05 http: TLS handshake error from [::1]:51240: acme/autocert: server name component count invalid
2023/01/22 17:58:06 http: TLS handshake error from [::1]:51241: acme/autocert: server name component count invalid

I don't know what happens. Who can tell me why?

You should use http://yourdomainname.com/ping. this package is used for redirect http request to https and meanwhile force you to use the domain configured to access. For use locally, you can edit your hosts, resolving domain name you like to localhost. As for server, you should buy several domain name that resolved to your IP and configure it in autotls.
