what iOS on iPhone, try different iOS version see if that works, may be the web portal may be not compatible.

try any other browser available in your phone - open the webpage manually and check ?

So it seems the EUP portal cert is not trusted by client (Iphones) how would I address this?

Go to Administration > Identity Management > Groups.

Find the repository where all the MAC addresses are stored and manually enter the MAC address of the iPhone.

This is affecting all iPhones in the facility. Also I have several guests
that come around and require connection.

If this affects "all iPhones" then it has something to do with the way the EULA is formatted.

Does this affect iPads?

To resolve the certificate trust issue, typically the best way to handle this is by obtaining a certificate from a globally trusted certificate authority such as DigiCert, Entrust, Symantec, Godaddy etc.

These issuers are globally trusted across manufacturers and are used to issue certificates for public websites.

You can order a certificate form a provider like this. You'd submit a CSR to the provider and receive a certificate back from them, which you could then bind to ISE and associate the desired portal tag to it.

Fixing the Cert Issue on ISE helped to fix this issue..
