проблема с IPv6

[gen555]

День добрый и спасибо за классный плагин :) Есть следующая проблема: При запуске bundle exec rake redmine_bots:telegram (как и других команд, инициирующих связь с сервером Телеграма) получаю ошибку подключения из-за отключенного IPv6:

Каким-то чудом удалось пройти авторизацию (возможно помогло увеличение TIMEOUT в скриптах, но вряд ли). Дальше дело не двигается. Можно ли как-то убрать попытки подключения по IPv6, если он отключен в системе, или хотя бы игнорировать ошибки подключения, перебирая другие сервера серверов?

В Debian 10 сделал так:

nano /etc/sysctl.conf

В конец файла добавил строки net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 net.ipv6.conf.ens192.disable_ipv6 = 1

причём вместо ens192 вставьте свой интерфейс

запустил команду

sysctl -p

И проблема ушла.
