Network errors and attacks are usually temporary, so this page will probably work later. You cannot visit right now because the website uses HSTS.
Your information is still secure because Chrome stopped the connection before any data was exchanged. This may happen when an attacker is trying to pretend to be, or a Wi-Fi sign-in screen has interrupted the connection. When Chrome tried to connect to this time, the website sent back unusual and incorrect credentials. normally uses encryption to protect your information.
Sometimes I can visit the site anyway, but other times it won't let me, and gives me a message like: Google Chrome on Macbook keeps giving me 'Your connection is not private' messages for websites that work perfectly fine on my PC (connected to the same internet) - like Wikipedia.
