Перестали работать все торренты, журнал подсказывает ошибки сети

Я использую Ktorrent на Ubuntu.

Я начал это сегодня, и мои незавершенные торренты остановились. Никакие разумные действия внутри приложения не могут их запустить. Нет сверстников. Это для разных торрентов из разных источников.

Файл ~/.kde/share/apps/ktorrent/logсодержит множество подобных вещей

Это намекает на какую-то проблему с начальной загрузкой или обнаружением пира, но я не знаю деталей.

Есть идеи, что происходит?
