Can't get Google CAL to work with iCAL "Server with a secure communication unavailable"

I can't add my google account to iCal...

Error message:

"Server with a secure communication unavailable"

"Your calendar acct isn't on a server that can receive your calendar information securely.."

I have had this work just fine in the past, had to remove my accounts a while back, decided to add them back, and this error keeps popping up...

Can anyone help??

Googled and Searched this forum with no success. Found some suggestions but nothing worked.

Thanks,
