http://localhost:8080/ kinda works

also previous examples in this tutorial worked perfectly

(2 examples:
https://go.dev/doc/articles/wiki/part1.go
and

package main

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

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hi there, I love %s!", r.URL.Path[1:])
}

func main() {
    http.HandleFunc("/", handler)
    log.Fatal(http.ListenAndServe(":8080", nil))
}```

I allowed it @ firewall

so it should work.. as previous example worked

(Windows 11 OS x64)

I've created file text.txt

it's got inside
