как видно из конфига сквид работает с авторизацией керберос в АД.

прокся тестовая, но на продуктивах в отличие от тестового есть еще ACL с блокировкой по сайтам.

проблема в том что и на тестовом и продуктивном прокси у многих пользователей не открывается сайт http://hh.kz

вот что пишет в логах когда на этот сайт подключаюсь я:

пробовали у разных юзеров в разных браузерах, проблема везде одинаковая. загрузка висит и обрывается. что странно у меня доступ есть, хотя как видно из конфига, он у меня такой же как у всех юзеров. кеш у себя и пользователей чистился неоднократно. Сам прокси не кеширующий. Может быть настройки браузера?

уже не знаю что делать, помогите разобраться с проблемой.
