@rcoleman-netgate Sorry, can not reproduce now this error to make screenshots. Did fresh reinstall of Windows 11 and for this moment no any warnings. That was standard error warning "your connection is not secure and site can steeling your sensitive data."))) Took a look on certificate of this site and was intercept with additional certificate from my ISP! No any idea , how it possible during using of VPN. My laptop was connected with VPN client (ExpressVPN) throw home router ((Router not from ISP and firmware is OpenWRT ) to pfSense box (pfSense plus 23.01 is installed on old laptop). But this warning start coming not immediately on fresh copy of Windows but a few days later. Now after reinstalling will watching out this situation again(((
