Подключили VPN и перестал работать Viber – есть решение этой проблемы.
Имеем Windows 11 на которой не работает «Вайбер» при подключении виртуальной сети VPN, которая настроена на ноутбуке для возможности работать во время путешествий и в командировках. Viber пишет – нет подключения к интернету, хотя оно есть, если например зайти через браузер на любую интернет-страницу, она открывается.
Решение оказалось очень простым:
Переходим в раздел «Параметры», далее «Конфиденциальность и защита».
Затем открываем раздел «Безопасность Windows» и переходим в раздел «Брандмауэр и безопасность сети».
Далее находим внизу строку «Разрешить работу с приложением через брандмауер» и там, в списке находим Viber. Нажимаем на Viber, а затем жмем «Изменить параметры» после чего становиться активной кнопка «Удалить» — удаляем Viber из списка и перезагружаем компьютер.
После этого Вайбер должен работать и при включении VPN.
Кстати, в этом списке приложений Вайбер оказался после последнего обновления.
