Hi

What is the address of the website that you are trying to view?

For many sites, you can bypass an invalid certificate, but most large/well-run sites block that because they want to have a secure connection with their users.

If you copy/paste the error page information -- particularly any ALL_CAPS_ERROR_CODE -- into a reply, that would be helpful in tracking down the source of the problem. Sometimes you need to click an Advanced button to access the details.

And for future reference: Troubleshoot security error codes on secure websites
