http.Handle not working in Golang

I try render a template:

func main() {
http.HandleFunc("/", index)
http.HandleFunc("/login", login)
err := fcgi.Serve(nil, http.HandlerFunc(handler))
}

func handler(w http.ResponseWriter, r *http.Request) {
   w.Header().Set("Content-type", "text/html")
   t, _ := template.ParseFiles("404.html")
   t.Execute(w, &page{Title: "not work"})
}

But when I open every page, even site.com/login, I see 404. Where can I find the problem?

fcgi package documentation explains

[...] If handler [second argument of fcgi.Serve] is nil, http.DefaultServeMux is used.

In order to make use of functions registered with http.HandleFunc in http.DefaultServeMux you should not pass second argument to Serve function otherwise the handler function will serve all requests.

func main() {
    http.HandleFunc("/", index)
    http.HandleFunc("/login", login)
    err := fcgi.Serve(nil, nil)
}
