Globalprotect for android ver 6.1.14 issue

[MRamadanAHafiez]

Hello Team,

                    I am recently having problem with GlobalProtect agent for Android phones.

previously everything was fine and no problems until version 6.1.11.x.

now upgraded to Globalprotect for android version 6.1.14.x.

since this version was installed o the mobiles, we are having problems connecting to the portal.

as soon as you click on the Connect you receive a message "Network connection is unreachable or the portal is unresponsive".

If I remove this version and back to the older 6.1.11.x it works back fine.

any other mobile phone with 6.1.11.x having no problems connecting to the portal.

any other globalprotect version 6.1.14.x can not connect.

Changes in my portal:

- applying policies based on a specific Host Information Profile only allowed to connect.

- according to security advisory we have stopped sending the firewall CA during the SSL VPN connection "supposed to affect on windows only".

- according to security advisory, we have a dedicated certificate for communication cookies between the mobile device and the portal.

- Globalprotect certificate is a self signed and used to accept it."also as in globalprotect for android ver 6.1.11.x.

We have PA-1410, Panos version 11.2.7-h4.

any ideas what's going on?

TIA
