I cannot access Linkedin. I use a Mac mini. I've tried from Firefox, Chrome and Safari. This is new, in the past week or so. I've tried using "linkedin.com" and various other links to specific pages, with no luck. Any clue what's happening here and how to fix it?
The error messages:
Firefox: "The page you are trying to view cannot be shown because the authenticity of the received data could not be verified."
Chrome: "www.linkedin.com unexpectedly closed the connection."
Safari: "Safari can't open the page... because Safari can't establish a secure connection to the server "linkedin.com".
