How to Fix Connection is Not Private Error in Chrome

Security warnings while browsing can be frustrating. In many cases, they are caused by a website that's not configured properly, but there are a few computer and Chrome browser settings we can check to ensure the problem isn't happening because of a mistaken setting.

This guide will take you through the basic settings to ensure your computer and Chrome aren't the cause of these security errors. We will check:

• Computer date and time
• Chrome cache and cookies

A Quick Fix

Security certificates are used by our web browsers and computers to make sure a particular site is safe. If the date and time are wrong, certain web pages may give security warnings and secure programs such as work VPNs, banking apps, and most social network apps will not function. Since iOS devices (iPhones and iPads) and Android set their time automatically, you don't usually need to check those.

If you notice that your Date and Time keeps becoming unsynced, you should speak to the manufacturer about replacing your CMOS battery.

How to Verify the Date and Time on a Mac

1. Select the time display in the top-right corner of your screen.
2. Make sure both the date and time are correct.
   
3. If the time is incorrect, select the time display in the top-right corner of your screen, then select Open Date & Time Preferences.
   
4. Select the lock in the bottom-left corner to make changes.
   
5. Enter your username and password, then select Unlock.
   
6. In most cases, letting your Mac take care of setting the time is the best choice. Make sure there is a check for Set date and time automatically, and make sure a time server close to you is chosen.
   
7. If you want, you can set the time manually. Remove the check for Set date and time automatically, then enter the correct date and time. Press Save when done.
   
8. Select Time Zone, then select your closest region on the map, and refine it by choosing the city you are in, or the city closest to you, from the list below.
