kotlin(Android) ошибка при отправки запроса на сервер

При нажатии копки Login выполняется функция:

fun goUserAccount(view: View) {
        val login = SpannableString.valueOf(findViewById<TextView>(R.id.login_user).text)
        val password = SpannableString.valueOf(findViewById<TextView>(R.id.password_user).text)
        val credentials = login.toString() + password.toString()
        val hashCredentials = byteArrayToHexString(MessageDigest.getInstance("SHA-1")
                .digest(credentials.toByteArray()).toTypedArray())
        var reqParam = URLEncoder.encode("hashCredentials", "UTF-8") + "=" + URLEncoder.encode(hashCredentials.toString(), "UTF-8")

        AsyncRequest().execute("/login?", reqParam)

        val  userAccount = Intent(this, MainActivity::class.java)
        startActivity(userAccount)

В ней вызывается AsyncRequest().execute("/login?", reqParam):

internal class AsyncRequest : AsyncTask<String, Int, String>() {
        override fun doInBackground(vararg p0: String?): String {
            val mURL = URL("http://192.168.0.22:8080" + p0[0] + p0[1])
            with(mURL.openConnection() as HttpURLConnection) {

                requestMethod = "GET"

                println("URL : $url")
                println("Response Code : $responseCode")

                BufferedReader(InputStreamReader(inputStream)).use {
                    val response = StringBuffer()

                    var inputLine = it.readLine()
                    while (inputLine != null) {
                        response.append(inputLine)
                        inputLine = it.readLine()
                    }
                    it.close()
                    println("Response : $response")
                }
            }
            return "";
        }
    }

Приложение падает на строчке println("Response Code : $responseCode") с ошибкой:

Подозреваю, что надо вызывать как то по другому, из другого потока, но как именно не знаю. Подскажите пожалуйста.
