DigiCert with Guest Portal - Not Trusted?

[Matthew Martin]

Hello All,

ISE v2.7

I just uploaded a new wildcard DigiCert certificate to ISE with the Role of Guest Portal. I uploaded the new wildcard cert + the private key that my manager gave me. I checked the Allow wildcard certs checkbox and everything appeared to update just fine.

So I then took my Android cell and connected to our Guest Wi-Fi. When I got redirected to the login page, I got the message: "The network you're trying to join has security issues."

When I click View Certificate in the browser window on my cell, it shows the portal login url, and says "This certificate isn't from a trusted authority". It shows Issued to: CN: *.mycompany.com and Issued by: DigiCertTLS RSA SHA@%^ 2020 CA1.

Why wouldn't DigiCert be considered a Trusted Authority? I'm confused...

Thanks in Advance,
Matt

how is your URL redirect FQDN

is this example : guestportal.mycompany.com ? or IP ?

do you have DNS entry guestportal.mycompany.com

Note : how about try other device ..part of testing ?
