Many HTTPS sites not working in chroium NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED

[Nikolay Morozov]

Geting the error like this :

Your connection is not private

Attackers might be trying to steal your information from mail.ru (for example, passwords, messages, or credit cards). NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED
  Automatically report details of possible security incidents to Google. Privacy policy
ReloadHIDE ADVANCED
mail.ru normally uses encryption to protect your information. When Chromium tried to connect to mail.ru this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be mail.ru, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Chromium stopped the connection before any data was exchanged.

You cannot visit mail.ru right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.
