Captive portal issue for Mac OS users

Hello Rajan

I see on your Mac's browser the URL doesn't contain the fgtauth key, which means that the active portal didn't open automatically, right? I mean the URL should be something like this.

https://1.2.3.4:5678/fgtauth?xxxxxxxxxxx

Try enter https://1.1.1.1 in your Mac's browser and the active portal should open automatically and properly.

Hi 

We tired manually triggering captive portal , but login page not displaying 

We are facing intermediate issue in portal , for only latest mac os versions 

Are you using a public certificate or a privately signed certificate to secure that portal? And does this behavior persist on the latest macOS version using different browsers?

From the screenshot it seems like captive portal certificate is not install on the CA repository of the MACOS.
Refer to the article:https://community.fortinet.com/t5/FortiGate/Technical-Tip-How-to-change-the-Captive-Portal-certificate/ta-p/196406 to change or check captive portal certificate.
