Problems connecting to Globalprotect after users install latest windows Cumulative updates

L1 Bithead

There seems to be a bit of an issue connecting to Globalprotect after our windows machines have the latest microsoft cumulative updates, KB5018410 (windows 10) and KB5018418 (windows 11).

Looking in reddit it looks like other users are seeing the same problem as well, anyone got any ideas on how to fix this going forward? The only way we've been able to get users to connect is by uninstalling the latest update.

I've raised a call with our partner support but havent got anything back yet.




Any news about 22H2  WIndows 11 ??

I had 5 users who were hard down due to GP in always-on mode. I had to uninstall manually with regedit to allow uninstall, then reinstall GP.

Below KBs from MS for Windows 11 have helped resolve the issue for other customers. Please check which version are you running and then try to apply the patch accordingly. 
KB5020387 fixed Win11 21H2

KB5018496 fixed Win11 22H2

The issue is related to the Azure SAML authentication. It was okay if the GP authenticated with the on-prem LDAP.


# Solution 1. Update the fixed KBs to the client systems.

1. Microsoft KB5020435 fixed the issue on Windows 10.
2. Microsoft KB5020387 fixed the issue on Win11 21H2
3. Microsoft KB5018496 fixed the issue on Win11 22H2


# Solution 2. Remove the installed KB5018410

If you want to fix the problem immediately, you can just remove this KB from the impacted system. However, the proper solution would be Solution 1 which is the bug fixes.


# Solution 3. Change the GP app configurations

'Use Default Browser for SAML Authentication' is set to No (by default).

If you change this option to Yes, you should be able to connect to the VPN. However, this change brings a browser pop-up window, and the user needs a few more clicks.


Hope this helps!
