“Your connection is not secure” message, how to fix it?
Fix – “Your connection is not secure”
Solution 1 – Check if your date and time is correct
One of the most common causes for Your connection is not secure message is incorrect date and time. Many websites use security certificates, and each certificate has its own expiration date. If time or date on your PC isn’t correct, your browser might detect the required certificate as outdated, thus giving you this message.
However, you can easily fix the problem simply by updating your date and time. To do that on Windows 10, you need to follow these simple steps:
- Right click the clock in bottom right corner and click on Adjust date/time.
- Date and time window will now appear. Turn off Set time automatically option.

- Press Windows Key + S and enter date. Select Date and Time from the list of results.
