Wont open a website I usually access

Hi

I just updated my mac to latest updates provided by Apple and now I cannot access a website that I have never had an issue with before. The new site now has a locked lock next to website address and it I click on it the following appears.

" Safari is using an encrypted connection to "yts.to" . Encryption with a digital certificate keeps information private as its sent to or from the https website "yts.to"

Is this why I have this issue? What do I need to do to access page?

Please help

Thanks in advance
