Crouton Ubuntu on Chromeos Certificate Error

Ok, so I've searched the forums looking for a guide that's neither Mac nor Windows. But there is none.

I've played 5 games on the Chromebook with 30 FPS at medium settings. But then it started having a certificate error when I log in. It opens up a security error window saying, "There is a problem with the certificate for this site. Do you want to continue?" When I click yes it opens up a second window that says more or less the same thing and when I say yes to that one it continues to ask me. When it finishes the Login Screen opens up a window saying, "Connect Error" etc. etc.
