Solution 3. Install Trusted Certificate

To Fix -Err_Cert_Invalid

This fix should only be employed if you are in very much need.

NET::ERR_CERT_AUTHORITY_INVALID как исправить

При переходе на какой-либо сайт (или ряд сайтов) пользователь может столкнуться с сообщением об ошибке «NET::ERR_CERT_AUTHORITY_INVALID», гласящим о незащищённости установленного сетевого подключения.

Обычно проблемное сообщение возникает внезапно, вынуждая пользователя гадать о сути и причинах возникшей дисфункции.

В данном материале я расскажу, как исправить ошибку NET::ERR_CERT_AUTHORITY_INVALID, перечислю причины данной проблемы и поделюсь вариантами её решения.

Ваше подключение не защищено в браузере

Причины ошибки NET::ERR_CERT_AUTHORITY_INVALID

В переводе с английского данное сообщение звучит как «сетевая ошибка, недействительный издатель сертификата». Обычно это означает ситуацию, когда сертификат данного сайта не вызывает доверия у вашего браузера, потому переход на данный сайт может быть заблокирован.

Наиболее часто данная ошибка возникает при работе браузера Google Chrome, который сигнализирует о незащищённости соединения и возможности доступа к нему со стороны злоумышленников, потому препятствует установлению соединения с таким сайтом.

Что относится к причинам ошибки NET::ERR_CERT_AUTHORITY_INVALID, то они могут быть следующими:

Сертификат не подан сторонним сайтом;

Ошибка нарушения конфиденциальности, статья по устранению по ссылке;

Поданный сайтом сертификат не корректный (в частности, устаревший);

Соединение между сторонним сайтом и вашим браузером небезопасно;

Пользователь использует устаревшую версию браузера.
Протокол SSL

Как исправить NET::ERR_CERT_AUTHORITY_INVALID

Какие способы могут помочь избавиться от ошибки NET::ERR_CERT_AUTHORITY_INVALID? Ниже я перечислю действенные способы решения проблемы, попробуйте выполнить каждый из них. Но сначала просто перезагрузите ваш компьютер – иногда причиной ошибки бывает случайный сбой в работе ПК, перезагрузка же системы позволит исправить данную проблему.

Проверьте корректность даты и времени. Регулярно встречающаяся причина рассматриваемой ошибки – это некорректное отображение компьютером текущей даты и времени. Часто это связано с исчерпанием срока действия элемента питания CMOS (CR2032), находящегося в материнской плате и ответственного за хранение текущих настроек БИОСа. Исчерпание ресурса упомянутой батарейки может вести к сбоям (потере) корректных настроек даты и времени, что, в свою очередь, приводит к появлению ошибки NET::ERR_CERT_AUTHORITY_INVALID. Если текущее системное время (или дата) некорректны, тогда попробуйте установить в настройках системы правильную дату и время (Панель управления – Часы, язык и регион — Установка даты и времени). Если дата и время постоянно «теряются» — замените элемент CR2032;
Устанавливаем правильную дату и время

Подтвердите переход на проблемный сайт. Если у вас старая версия Хром (или другого браузера), а сайт, на который вы перешли, проверенный, тогда просто нажмите на кнопку «Proceed anyway» (перейти в любом случае). Браузер укажет вам, что данное соединение не внушает доверия (This Connection is Untrusted). Нажмите на кнопку «Добавить в исключения» (Add exception), после чего сертификат данного сайта будет добавлен в исключения, и данная ошибка больше не будет возникать.

В новой версии браузера Хром (и других браузеров) вам необходимо будет нажать на «Дополнительно» (Advanced) на экране ошибки. Перед вами откроются дополнительные опции, в которых вам будет необходимо найти опцию для подтверждения перехода на данный сайт (Proceed to site — unsafe). Кликнув на неё, вы будете перенаправлены на данный сайт;

Если адрес проблемного сайта начинается на «https» (защищённое соединение), попробуйте сменить начало адресной ссылки на «http» (без «s») и в таком виде перейти на сайт, это может помочь исправить ошибку NET::ERR_CERT_AUTHORITY_INVALID;
HTTP протокол

Временно отключите ваш антивирус. В некоторых случаях он может блокировать переход на нужный сайт;

Включите игнорирование проблемного сообщения. Кликните правой клавишей мыши на иконку браузера, выберите «Свойства». Во вкладке «Ярлык», добавьте к содержимому строки «Объект» следующее: -ignore-certificate-errors- затем нажмите на «Применить», и «Ок»;

Игнорируем ошибку с сертификатом в браузере

Очистите кэш и данные вашего браузера. К примеру, в Хром это делается нажатием на кнопку настроек, в появившемся меню выбираем «Дополнительные инструменты», а в них «Удаление данных о просмотренных страницах». Ставим галочки на нужных пунктах, и нажимаем кнопку «Очистить историю»;
Удаляем кэш браузера

Временно отключите все расширения (дополнения для вашего браузера). Если после этого вы без проблем перейдёте на ранее не доступный ресурс, попробуйте включать расширение по одному пока не найдёте проблемное расширение, вызывающее проблему;

Попробуйте выполнить вход на сайт с другого браузера. Если переход пройдёт без проблем, сбросьте настройки ранее проблемного браузера, или полностью переустановите его.

-решение

Эффективным ответом на вопрос «NET::ERR_CERT_AUTHORITY_INVALID как исправить» станет использование комплекса решений, описанных мной выше.

Наибольшую эффективность среди них показало внесение сертификата проблемного сайта в исключения браузера, а также метод игнорирования возникающей дисфункции с помощью изменения содержимого строки «Объект» в свойствах ярлыка браузера.

Попробуйте весь перечень указанных мной инструментов, они позволят эффективно избавиться от ошибки CERT_AUTHORITY_INVALID на вашем ПК.
