Сетевая программа с многопоточностью отлично работает на windows, но не работает на linux

Question

Недавно я столкнулся с проблемой, связанной с запуском программы python на linux. Я написал сканер IP для локальной сети (как и arp-scan), который отлично работает на windows, но выдает ошибку (см. Ниже) при выполнении программы в оболочке linux (fedora). Якобы эта проблема связана с многопоточностью или tcp? Я также проверил версию python, которая точно такая же в Fedora и windows (3.7). Кроме того, в сообщении об ошибке говорится: «сеть недоступна», хотя сеть работает на все сто процентов (youtube, github ...)

Эта проблема сводит меня с ума, может ли кто-нибудь помочь?

In ниже вы можете найти код и данную ошибку.
