forigate 81f Certificate applied but still showing Not Secure
Recently got an 81f installed and I generated a Certificate and applied it to the Fortigate Administrative, users, and VPN settings, but when I connect to the Fortigate, I still get the Not Secure warning on any browser (Edge, Google, Firefox). When I check the certificate on Chrome, it shows that it is not a valid certificate and that it was generated from Let's Encrypt and shows the generated date, and expiration date. Any ideas on where to look for troubleshooting this issue?
