Когда я пытаюсь подключить свой esp8266 к ngork с помощью arduino ide, ngrok говорит: ошибка 502 плохой шлюз, он открывает localhost: 4040 и я использую порт 8080, это проблема?Если я использую порт 4040, у меня есть другая проблема: 404 Не найден на ngrok

Я не могу найти решение, на данный момент ngrok отвечает следующим образом:
