Error Code “DLG_FLAGS_INVALID_CA” Windows 10/11
When you visit a webpage or the homepage of a website, instead of loading the page, you receive an error that reads This site is not secure – Error code: DLG_FLAGS_INVALID_CA DLG_FLAGS_SEC_CERT_CN_INVALID in Microsoft Edge, Internet Explorer, Google Chrome, or Mozilla Firefox on Windows 11 or Windows 10. This guide explains what the error indicates and what you can do to get rid of it.
What does the “DLG_FLAGS_INVALID_CA” and “DLG_FLAGS_SEC_CERT_CN_INVALID” error code mean?
To fix the issue, first, you will have to understand what this error is about. Whenever you see the “This site is not secure” error regardless of the error code, it implies that there is an issue with the website’s certificate if the website is running HTTPS.
If you are particularly getting the DLG_FLAGS_INVALID_CA DLG_FLAGS_SEC_CERT_CN_INVALID error code in Windows 11/10, it could mean a few things:
- The website’s certificate cannot be recognized by your browser.
- The website’s certificate is either expired or not installed correctly.
- The website is using HTTPS without a proper certificate installed and pretends to be secured.
The error basically indicates that there is an issue with the website’s certificate if it has one. A website’s certificate is controlled by the administrator or owner of the website itself. Therefore, there is really nothing you can do about it if the error is with the website’s certificate.
This error often occurs when a website’s admin forgets to renew its certificate, thus causing This site is not secure error code DLG_FLAGS_INVALID_CA DLG_FLAGS_SEC_CERT_CN_INVALID to its readers whenever an HTTPS page is requested.
What are the options available?
When you see the “This site is not secure” error, particularly the DLG_FLAGS_INVALID_CA error code, you would usually see the following two options:
- Back to safety or Go to your start page link which will redirect you to the previous webpage or to your default starting page of your browser. This is usually the recommended option so that you don’t get into trouble by visiting sites that very much can be malicious if the certificate is incorrect.
- By clicking on Advanced then Continue to this website or Proceed anyway link will ignore the warning and proceed loading the webpage regardless of its unrecognizable certificate. This is not recommended on websites that you can’t tell if they are trustworthy.
However, there can also be a few situations where the certificate of the website is legitimate and running fine but you’re still getting the error. If that’s the case, especially if you get the same error across all websites you try to visit, or are visiting some websites that you are sure can be trusted, here’s what you can do to fix the issue.
Check the date & time
ncorrectly set date and time on your Windows PC are one of the most common reasons for SSL and certificate errors when you visit any HTTPS website. This is because when your browser tries to read the certificate to decide if it’s safe to visit the secured page, it will first check on its date to see if it matches your local date and time. If it doesn’t, it will show a certificate error such as This site is not secure error code DLG_FLAGS_INVALID_CA DLG_FLAGS_SEC_CERT_CN_INVALID error.
To check your date and time, in Windows 11/10, right-click on the date and time on your taskbar. Select Adjust Date/Time. Enable the set time automatically option to allow Windows to automatically sync your time with Microsoft server so that your PC will always show the most precise time.
Clear your browser’s cache
Another reason that the error code DLG_FLAGS_INVALID_CA would show up is when your browser is trying to load a cached version of the webpage instead of reloading the updated version of it when there have been changes. For example, if the website has already renewed its certificate but your browser is still showing the older version of the website because of an existing cache on your browser, you will likely still see the error.
Try to clear your browser’s cache and see if it fixes the DLG_FLAGS_INVALID_CA DLG_FLAGS_SEC_CERT_CN_INVALID error on Microsoft Edge, Google Chrome, or Mozilla Firefox.
The steps to clear browser’s caches vary from browser to browser. The option is usually in the Settings or Options page of your browser. For example, in Chrome browser, click on the option button at the top right corner of Chrome’s window and select Settings. Search for cache and select “Clear browsing data“. Clear the “Cookies and other site data” and “Cached images and files“.
As for Microsoft Edge, go to Settings, then Choose what to clear. For Firefox, click on Options, then clear cookies and cache.
After clearing your browser cache, retry visiting the problematic website again.
Try to use another web browser
If the issue happens in Edge, try to use a different browser such as Chrome or Firefox. The issue may sometimes be with your default web browser. The causes can be plugins or extensions you’ve installed, incorrectly configured browser settings, faulty proxy settings, or an outdated browser.
If the website loads fine on another browser, you may want to reset your problem browser to default to try to fix the This site is not secure error code DLG_FLAGS_INVALID_CA DLG_FLAGS_SEC_CERT_CN_INVALID issue in Windows 10/11.
Как исправить ошибку сертификата DLG_FLAGS_INVALID_CA в Windows 10?
Во время серфинга в интернете иногда не удается посетить некоторые сайты, когда вместо загрузки страницы получаем сообщение: Этот сайт небезопасен — Код ошибки: DLG_FLAGS_INVALID_CA DLG_FLAGS_SEC_CERT_CN_INVALID. Рассмотрим несколько простых решений, с помощью которых можно ее исправить.
Причины блокировки доступа к сайтам ошибкой DLG_FLAGS_INVALID_CA
Чтобы устранить проблему, нужно узнать, чем вызвана эта ошибка. Когда видите ошибку «Этот сайт небезопасен», независимо от того, с каким ее кодом сталкиваетесь, это означает, что возникла проблема с сертификатом сайта, если он работает по протоколу HTTPS. То есть, доступ к содержимому может быть заблокирован по следующим причинам:
- Браузеру не удается распознать сертификат.
- Срок действия сертификата истек, или он установлен неправильно.
- На сайте обнаружено вредоносное перенаправление.
Исходя из причин можно предположить, что браузер выбрасывает ошибку DLG_FLAGS_INVALID_CA, чтобы предотвратить проникновение вредоносного контента на компьютер.
Во многих случаях, когда ошибка связана с окончанием сертификата посещаемого сайта, то ничего не сможете с ней сделать. Но иногда она может возникнуть из-за проблем с обозревателем, который используете для серфинга в интернете. В этом случае попробуйте следующие решения для ее исправления.
Очистка кэша браузера
Если не удается открыть определенный сайт, возможно, браузер пытается загрузить кешированную страницу вместо перезагрузки ее обновленной версии, в которую были внесены изменения. В этом случае выполните очистку кэша браузера, и после его перезагрузки снова попробуйте посетить ту же страницу.
Если используете Google Chrome, в адресной строке наберите chrome://settings/clearBrowserData и нажмите на «ОК». Проверьте, что отмечена опция Изображения и другие файлы, сохраненные в кэше. Запустите нажатием на кнопку «Удалить данные».
В Microsoft Edge откройте основное меню нажатием на значок с тремя точками и перейдите в настройки. На панели слева выберите вкладку «Конфиденциальность, поиск и службы». В правой части найдите раздел «Удалять данные о просмотре веб-страниц» и щелкните на кнопку «Выбрать элементы для удаления».
Проверьте, что установлена отметка на опции «Кэшированные изображения и файлы» и запустите очистку.
Проверка доступа к сайту в другом браузере
Если продолжаете сталкиваться с ошибкой DLG_FLAGS_INVALID_CA, возможно, возникла проблема в самом браузере. В этом случае попробуйте посетить тот же сайт с другого браузера. Если страница открылась без ошибок, попробуйте сбросить настройки до значений по умолчанию.
В Chrome откройте основное меню и перейдите в Настройки. На левой панели перейдите на вкладку «Сброс настроек и вредоносного ПО». Затем выполните восстановление настроек по умолчанию.
Проверка даты и времени
Неправильно установленные дата и время — одна из наиболее частых причин ошибки SSL при посещении любого сайта на HTTPS. Когда браузер пытается считать сертификат, чтобы проверить, безопасно ли посещение защищенной страницы, он сначала проверяет его дату и время. Если они не синхронизированы, система выбросит ошибку сертификата DLG_FLAGS_INVALID_CA. Для исправления выполните следующие шаги.
На панели задач Windows 10 щелкните правой кнопкой мыши на часы. В меню выберите «Настроить дату и время».
В окне настроек включите параметр «Установить время автоматически», чтобы позволить Windows синхронизировать время с сервером Microsoft.
Затем проверьте, когда в последний раз выполнялась синхронизация системных часов. Если это было сделано давно, нажмите кнопку «Синхронизировать сейчас». Также убедитесь, что часовой пояс указан правильно.
Отключение предупреждения о несоответствии адреса сертификата
Откройте поисковую строку Windows и введите «Свойства браузера». Когда они отобразятся в результатах поиска, щелкните, чтобы открыть.
В окне свойств интернета перейдите на вкладку Дополнительно. Здесь найдите опцию «Предупредить о несоответствии адреса сертификата» и снимите флажок.
Примените изменения и перезагрузите ПК. Проверьте, блокируется ли вход на страницу ошибкой DLG_FLAGS_INVALID_CA.
