Hi everyone,
I’m having an issue with my SSL/TLS certificate when setting up a captive portal for Wi-Fi authentication.
1. I imported my company domain certificate (fullchain.pem and privkey.pem) under System > Certificates. 2. The import works fine, it shows valid dates, status OK, and everything looks good.
3. The certificate also appears correctly under System > Settings > HTTPS Server Certificate and under Server Certificate.
However, when I try to configure Single Sign-On (Service Provider Configuration), the certificate does not appear in the list.
This certificate was generated using Let’s Encrypt (Certbot) and it’s a wildcard certificate.
My FortiGate is running version 7.6.4.
I want to use this certificate for the Wi-Fi captive portal, so that users are redirected to a company domain like auth.wifi.company.com during authentication.
Has anyone experienced this before or knows why the certificate doesn’t show up in the Service Provider Configuration section?
Thanks in advance!
