Помогите OSError: [WinError 10048] Обычно разрешается только одно использование адреса сокета (протокол/сетев

Пытаюсь настроить работу с плагинами на Python по этому уроку -

Спойлер

Плагин подключается, но список команд не выводится и они не работают.

При "ручном" прогоне плагина выходит ошибка -

Код:

Spigot выдаёт при этом ошибку -

Что нужно исправить, настроить?

 

Какой ужас. Совсем поехавшие .

 

Подскажите направление хотя-бы ...

 

Скажи что ты хочешь

 

Java

 

Как точно подмечено

 

x2

 

P.s го рисовать плагина на luaj .

 

Да месье знает толк в извращениях
