Runing server on Windows without deal with the Firewall - server

Question

Why is the firewall constantly asking for http permission for any programms where you need run something in localhost?
When running this example, permission will be asked each time (P.s. Using "go build -o a.exe && a.exe" (Using Go as an example) or something similar may sometimes not help)
Example 1
package main;
import (
"net/http"
"fmt"
)
func requestHandler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello, world")
}
func main(){
http.HandleFunc("/", requestHandler)
http.ListenAndServe(":6060", nil)
}

Answer 1

In any program where you work with a specific port, where a new executable file is created each time during implementation, the firewall will consider it as a new file and will ask for permission, the solution is the following:
Go to Windows Defender Firewall, in Left side menu you saw Inbound Rules click there
Then Right Side menu you will see New Rule... click.
Choose Port opened from window -> Next Select TCP, then define which ports you want I choose 6060 click Next again, Choose Allow the connection Next, Check All Next, Give any Name Goland or anything you want and press Finish. Thats it
