If both the portal and the gateway are configured with the same authentication method, this problem will not occur. At the time of authentication on the portal, user credentials are passed from the portal to the gateway. I have tried turning off the Hub 3 firewall and have had my firm’s IT team replace my laptop (Thinkpad Yoga X1 running Windows 10) but to no avail. Authentication works for GlobalProtect Portal but fails on GlobalProtect Gateway. We have tried fresh installs of GP and doing a reissue of the machine and client certs all give us the same behavior. If I keep GlobalProtect turned off I have no internet connection issues, I also have no issues with any of my other devices. The client will begin updating automatically after connection, with the notification GlobalProtect agent upgrade is in progress. Connect to the GlobalProtect VPN Client as usual. Our GP setup has prelogin using a machine certificate and then login using client certificate along with usernname/password then MFA. This manual should be used to automatically upgrade the Teachers College GlobalProtect VPN on a Windows 10 device. We are running GP 5.1.6 but have also tried 5.2.5 and 5.2.6 with the same results.
GLOBALPROTECT WINDOWS 10 ISSUES UPDATE
We confirmed that after uninstalling the windows update GlobalProtect behavior returned to normal, however these windows updates have critical security patches so uninstalling them isn't a good option. After installing the April 2021 windows updates our GlobalProtect clients started having issues connecting where it would take several attempts to get connected normally seeing 3-4 connect then disconnect cycles before finally staying connected.
