can't get to web interface

we use self-signed default ssl cert for our ADManager Plus.   normally we have to click "advanced" and then "continue to this webpage" in chrome... but in the last few months the "continue to this webpage" doesn't appear in Chrome, but was working in Edge.  now in Edge it's gone too!     has this happened to anyone else?  the self-signed cert is expired.. (about 2 years ago!).    can someone help?,
