Why can't continue browsing in IE11 when there is a certificate error?

Question

Browsers

At some point, on some https pages, the ability to continue browsing even with a certificate error stopped working. The button just disappeared.

You can’t add a certificate to trusted ones or view it, because there is no red icon at the top, if you go to the properties through ALT, the button does not respond to clicks Checked

everything a hundred times, disabled all policies related to IE, reset the settings to default.
The site tried to add to trusted nodes, but this is clearly not the case ..

Answer 1

Installed 4.0R2, all sites started working normally

Answer 2

on https this site does not exist at all
Turn on the use of TLS version 1 in the IE settings - Properties -\u003e Advanced - ...
True, you still will not see this particular subdomain on https, it is not there at all.
