Hi Experts,

Setup:
ISE 2.7 two node setup
Have a guest SSID with sponsored portal login.

Issue
Now when guest connect to this SSID, the ones that are using either Chrome browser or iOS devices, get this error.

While all users using IE or android devices, do not, they just get a certificate warning and are able to bypass this error and login to guest portal.

Has any seen this error before?
Any suggestions?

Hi,

This is a security feature in the browser when it detects captive portal
with untrusted certificate. Best solution is to install CA signed
certificate for guest portal.

Is there any other way to bypass this and just get a certificate error instead?

Its a browser level setting so its unique to every device.  No way to prevent this for guest devices which you do not have control of the settings.
