Fix Error “Your Connection is Not Private” on macOS Mojave


Fix Error Your Connection is Not Private on macOS Mojave

Overview: Today in this article we are going to troubleshoot an error “Your connection is not private”. There are any Mojave users who are having a hard time to open most of the sites because of this error.

Let’s Start with Few Practical Scenarios

Scenario 1: Your connection is not private browser errors after Mojave upgrade (And can’t connect to App Store)

I upgraded to Mojave and now when I visit certain websites (Facebook as one example) I receive this error: Your connection is not private. Attackers might be trying to steal your information from (for example, passwords, messages, or credit cards). Learn more normally uses encryption to protect your information. When Google Chrome tried to connect to this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Google Chrome stopped the connection before any data was exchanged. You cannot visit right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will I tried the tips I found online: Set Date/Time automatically, clear Chrome browsing history/data/cookies/etc. I restarted Chrome and the computer. I can’t check my virus software because my IT department has it locked down and they’re slow to respond to my plea for help. I tried Safari and Firefox browsers too BTW and have the same issue. Also, I can’t connect to the App Store anymore either. Has anyone found a solution to this problem?

Scenario 2: Certificate Error on Every Website/Browser

Hi there, I have been having an issue for the last couple of days. Whenever I visit a website (about 80%) of the sites I go to regularly, I am now getting an error that “Your connection is not private”. I have searched the entire internet for the answer and nothing has worked. This happens in Firefox, Safari, and Chrome. I have never ever had a problem with a Mac and now I am 100% lost on how to fix this…your help would be hugely appreciated!
