I have a HP Officejet Pro 8600 Plus Printer (2012). I am using a 2019 iMac computer with Catalina OS 10.15.7. I am trying to access the Embedded Web Service. When I go the sys pref, printer/scanner, Options & Supplies and select Show Printer Webpage, I get a popup stating the Connection is not private and to view the Certificate, when I do that it says that the certificate expires in March,2030. It also says This certificate has not been verified by a third party. I have updated the firmware on my printer along with the software update.
