For the past 4 days, I was having issues accessing some websites like facebook.com, dropbox.com and few others on Google Chrome and Internet Explorer. Each time I try to access these sites, I was presented with a certificate error as shown below:
Your connection is not private
Attackers might be trying to steal your information from www.facebook.com (for example, passwords, messages, or credit cards).
www.facebook.com normally uses encryption to protect your information. When Chrome tried to connect to www.facebook.com this time, the website sent back unusual and incorrect credentials. Either an attacker is trying to pretend to be www.facebook.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.
You cannot visit www.facebook.com right now because the website sent scrambled credentials that Chrome cannot process. Network errors and attacks are usually temporary, so this page will probably work later.
After searching the web for solutions, most of which where pointing to system time not in sync. I checked mine several times and can confirm it was up to date. For some users, the time was the issue while others it wasn’t.
OK I finally fixed mine and funny enough the error itself was actually telling me the root cause. For unknown reasons, the root certs where messed up so I had to clear all certs on my machine and rebuild new once using this Microsoft fix it tool.
Visit this site (http://support.microsoft.com/kb/931125), scroll to the end and click on the Fix It icon and everything will be sorted :).
