Сбой VPN соединения

[Фраисия]

Само подключение есть, но страницы не загружает. Через несколько минут соединение обрывает и пишет "сбой впн соединения...". Паралельно ещё установлен win7, там тоже написано "без доступа к интернету". В техпождержке сказали, что настройки верные, но пч не работает не знают. В терминале ввела команду sudo tail -f /var/log/syslog вот что выдал,помогите кто разбирается
