Unable to connect to the Global Protect on new Windows 10 build.

L4 Transporter

Hi All,


A client has run into a strange intermittent issue with GP clients not connecting correctly on a new build of a Windows 10 laptop. The issue also randomly happens on some existing domain machines. 


Basically, the GP client doesn't connect the first time when logging in with a domain account and a registry key needs to edited and / or the Windows credentials need to be added to Windows credential manager to resolve the problem.


I see an 'invalid portal' message in the PanGPA log and a message that the user cant open there Pan_PUAC (see below):


Failed to open file C:\Users\username\AppData\Local\Palo Alto Networks\GlobalProtect\PanPUAC_121620b54af6157948988a44540f448.dat


Client has provided the below workflow:


I just setup a new machine and the following occurred.


I logged into a machine Dell XPS 13”Win 10 latest edition as a new local user

Installed GP


Connected to VPN using duo auth


GP wanted to update and did. Then I reconnected GP.


Connected machine to work domain


Rebooted machine


Connected to VPN as local user


Locked machine using control alt del


Selected other user and typed in creds for new user


User profile created.


Rebooted machine


Logged in as new domain user and tried to access VPN.


Oops error occurs and you can’t login.


So you follow steps here https://goddamnpc.com/vpn-error-the-computer-must-be-trusted-for-delegation-and-the-current-user-acc...   and reboot


Then VPN connects after password and duo verification and you get the success and green tick.


After that the grey world just has the dots running around for ever and you never connect.


Sometimes, disconnecting and reconnecting gives you a connection sometimes not.


If all else fails you then add the domain user and password to the cred manager windows and that seems to fix the problem.


This issue has only recently been happening. So I’m not sure where the issue lies.


Has anyone come across or experienced this issue before?
