#5, still getting the error when I am not logged in on both the forum page and portal, when logged in the page displays without an error message.
From IE help:
I'm getting errors on websites I always visit, what should I do?
If you encounter a certificate errors at a website you have visited before without errors, it's possible the website is not configured correctly. Try retyping the address you are using. For example, if you are typing the address as https://example.com, try changing it to https://www.example.com.
It is also possible that the website's certificate has expired and the owner or operator needs to renew the certificate in order to continue using it.
