The only way to get rid of the certificate error is to obtain a public certificate.  The CN of the certificate (FQDN) also needs to resolve in DNS to the controller VIP that the clients obtain via dhcp.

What is the URL? and if you look at the certificate from the browser, that helps to determine what the issue is.

Thank you very much,

everything is working correctly thanks to your help, after resolving the captive portal's IP in the DNS server.
