Firefox не может загрузить страницу в 16.04

В моей системе работает Ubuntu 16.04 LTS, и с тех пор я начал сталкиваться с какой-то странной проблемой. Много раз, когда я пытаюсь открыть веб-сайт в своем браузере (Firefox), мне говорят «Сервер не найден», и только после обновления страницы много раз я могу попасть на веб-страницу. Эта проблема не возникает всегда или для каждого веб-сайта одновременно, но это происходит достаточно часто, чтобы раздражать меня.

Может ли кто-нибудь пролить свет на это?

PS. Эта проблема кажется уникальной для 16.04. Я использую подключение к локальной сети, и никто другой, использующий это соединение, не имеет этой проблемы (ни один из них не работает с 16.04). Кроме того, у меня было 12,04 до того же времени, и он работал нормально.

Сначала проверьте Network Manager. независимо от того, включен ли ваш IPv6 или нет, не уделяет особого внимания, но когда ваш IPv4 находится в статике, вы получите проблему. Убедитесь, что ваш IPv4 находится в режиме получения для динамического IP-адреса. затем просто отключите Windows и включите его на несколько секунд, чтобы обновить. Затем снова откройте свой браузер.

Вероятно, вы столкнулись с проблемой DNS, в основном вызванной медленными локальными DNS-серверами. Вы можете узнать свой текущий параметр DNS, вызвав:

 nmcli dev show | grep DNS 

Попробуйте настроить DNS на что-то вроде 4.2.2.4 .


Для лучшего диагноза выполните следующие действия:

Сервер не найден – Устранение неполадок подключения

https://support.mozilla.org/en-US/kb/server-not-found-connection-problem

Вы должны протестировать другие браузеры, и в результате вы сможете точно определить корень проблемы. Но согласно тому, что вы сказали, самая высокая возможность – проблема DNS. Это можно исправить с помощью предварительной выборки DNS, хотя у нее есть некоторые недостатки.
