Скрипты очень долго запускаются в тестовой сети kovan?

Question

Я развернул свои смарт-контракты в тестовой сети Kovan, и они успешно развернуты, я выполнил транзакцию с использованием метамаска в тестовой сети Kovan, и она успешно выполнена, а также нет ошибок, связанных с разработкой, что может быть причиной того, что это занимает так много времени для развертывания. Также сценарии успешно работали во время разработки, приветствуется любая помощь

мои scripts.js
