What is wrong? TLS

2. Thanks for replying

No love. Under Certificate Status it says : No Information Available. Unable to obtain identification status for this site. This is happening with Firefox, Edge and IE 11 but not Vivaldi. I do have TLS 1.2 checked in Internet Properties > Advanced > Security. The only other site affected (as far as my bookmarks are concerned anyway) is the one for my pre-paid debit card. Should I be concerned about that? No I don't have access to another machine, guess I could run up to the library later on but am puzzled by this. Oh, and the add exception box/tab is grayed out so can't do that either. Using same F.F. version you are.

Not a noob with computers but networking/internet is sorta my weak point. Any other advice? Thank you btw.
