1
Make sure your computer's date and time settings are correct. One of the most common reasons for getting an SSL certificate error is having your computer's date and time set to an incorrect day, week, month, year, and/or time. Check your computer's clock and calendar, and make sure your settings are correct. Consider setting your date and time zone settings automatically. This will make sure your computer will update your date and time settings automatically. On Windows, right-click the date or time on the bottom-right corner, select Adjust date/time, and slide the Set time automatically switch to On. On Mac, click the date or time on the top-right, select Open Date & Time Preferences, and check the Set date and time automatically box.
