DENO UDP Datagram Connection Socket не получает ответ на Linux ⇐ Linux

[Anonymous]

Итак, в основном я начал небольшой проект, включая Yeelight вчера. Система Linux. Все работает, но Дено не ловит никаких ответов. И из Wireshark устройство Yeelight отвечает на мою систему, Deno, кажется, просто игнорирует его. Так что это не должно быть проблемой устройства или сети. < /P>
Я что-то упускаю?

Обычно у меня есть проблемы с запуском кода в Windows, а не на Linux lmao
