When i run this code

package main

import (
	"context"
	"fmt"
	"net"
	"time"

	"github.com/Ullaakut/nmap/v3"
)

		if err != nil {
			results[port] = false
		} else {

				results[port] = true
				_ = conn.Close()
			} else {
				results[port] = false
			}
		}
	}
	return results
}

Hi @wowlikon ! Which version of nmap do you use? Is it available in your PATH?
