iphone not able to connect to Global protect

[Sidhesh.Parab]

iphone not able to connect to Global protect, however things works fine on Android, windows, Mac and other OS. I do have settings on VPN portal set to on-demand. 

I'm using SAML for authentication. I see that the portal authenticates the user, request reach vpn gateway before-login (gateway prelogin) SAML request is sent and later no logs logs.. Ideally it should be gateway-auth next with cookie receive from the gateway. Not sure why it is no happening

Hi @Sidhesh.Parab ,

I recommend reviewing the GlobalProtect logs on the iPhone immediately after reproducing the issue. Since the portal authentication succeeds but no request appears in the gateway logs, the failure is likely occurring before the gateway authentication request is completed.

With an On-Demand configuration,

I would normally expect the user to authenticate directly to the gateway rather than use a pre-logon workflow. The iPhone logs should help confirm why the app is attempting pre-logon and whether it is failing while processing the portal configuration or authentication cookie.
