Сервер доступен через SSH и HTTP на всех машинах, кроме одного клиента

Редактировать 3:

Странное открытие. Эта проблема возникает только у одного конкретного клиента. Все три сайта доступны через доменное имя с любого компьютера, кроме моего основного рабочего стола. Этот рабочий стол может получить доступ к серверу (для HTTP или SSH) только через локальный IP-адрес 192.168.0.X, но не через внешний IP-адрес или имя (а) домена. На всех других машинах все работает, как ожидалось.

Я проверил свои журналы fail2ban и брандмауэр, чтобы убедиться, что эта конкретная машина не блокируется. В чем еще может быть проблема? Это огромная боль - не иметь доступа к моему серверу с моего основного рабочего стола.

Оба жестко подключены к одному и тому же маршрутизатору через Ethernet-кабели, если это имеет значение.

Исходное сообщение:

У меня есть три виртуальных хосты, определенные в Apache (все три с файлами .conf, хранящимися в / etc / apache2 / sites-available , которые были включены через a2ensite ).

До обновления с Ubuntu 16.04 до Ubuntu 18.04 все три работали нормально. После обновления ни один из них не загружался в браузере, поэтому я проделал большую работу по устранению неполадок. Вот что я сделал / перепроверил до сих пор:

• Переустановлены apache2 и php
• Проверены apache2.conf , включая запуск apache2ctl -t для отладки - ошибок нет.
• Проверены файлы conf для каждого сайта, запустил apache2ctl -S , чтобы убедиться, что все распознаны. Каждый указывает ServerName (имя домена) и DocumentRoot (локальный каталог). Эти значения были трижды проверены на правильность.
• Проверены настройки DNS. Все три доменных имени указывают на правильный IP-адрес (для подтверждения использовался dig ).
• Проверенные настройки брандмауэра - порт 80 открыт, и Apache его прослушивает.

При доступе к любому из три сайта по имени домена, браузер выдает сообщение об ошибке: «Этот сайт недоступен. domain.com слишком долго отвечал».

Я могу получить доступ к сайту по умолчанию (первый загруженный Apache) с нет проблем, если я введу IP-адрес в браузере вместо имени домена.

Мне кажется, что это какая-то конфигурация Apache, которую я как-то испортил, но все, что у меня есть, это стандартный apache2.conf из новой установки вместе с файлами конфигурации виртуального хоста, которые имеют следующий формат:

<VirtualHost *:80>
    ServerName somedomain.com
    DocumentRoot "/var/www/foldername"
    <Directory /var/www/foldername>
        Options -Indexes
        AllowOverride XXXXXXXXXX
    </Directory>
</VirtualHost>

AllowOverride - None для одного сайта и Fileinfo Options для двух других. .

Есть идеи, что мне не хватает?
