Checkout the first question on
the FFF FAQ list.
UPDATE:
The FAQ was a little sparse, so I've gone back and expanded it some. It now reads:
I'm having SSL certificate errors--help?
SSL is becoming more and more common. But SSL certificates don't last forever. Lately, we've seen several users and more than one site that started getting errors after an SSL certificate was expired, renewed, or replaced.
SSL verification is a complicated process involving more than one certificate at more than one level, all of which eventually expire.
When a site's SSL certificate expires, you will also see an error visiting the site with your browser. All you can do in that case is wait for the site administrators to renew their cert. If you have a way to contact the site administrators, you could also notify them about the issue.
You can also get an error when any of the 'signing' certificates expire. Copies of some of these reside on your computer require periodic update to stay current.
So far, most of those users that have had issues with on-computer certs have been on Windows and the problem has been corrected by visiting the site giving problems using the Microsoft browser (IE or Edge) on your computer. That seems to automatically update the operating system's certificate store and make things work again.
