i found this website that enable you to generate a free Certificate for your controller
you can use this certification with the controller access webpage, captive potral and 802.1X terminition.
you can found in attachment the procedure to integrate the certification with captive portal and the controller webpage.
this way you will never get the certification error message.

You can get a public certificate that’s valid for 1 year for $4.99.
It’s not recommended to use LetsEncrypt certificates for these functions, especially EAP server certificates.
