ISE Guest port certificate error

[Mateen Ahmad]

Hello,

I have deployed 2 ISE2.4 nodes in HA and Running TACACS+ and Radius services.

Now as per client requirement he wants to enable Guest services as well.

Please know that I am using management IP of ISE node for Radius and Tacacs both and I have public cert deployed in ISE. 

Pblm: Guest user is facing certificate error on browser, using public DNS IP. Kindly help

Please follow ISE Guest Access Prescriptive Deployment Guide  > Setting up a Well-Known Certificate

After that, need updating the ISE guest web portal to use the certificate tag.

Note: Port 443 will still use the one designated for "admin".
