Addtitional Resources:  Feedback from the College of Engineering IT Staff indicated that these two options did not work for a related incident that one of their users encountered. Temporary KB0019166 has been created to provide links to other documentation that may assist in resolving this particular issue. 

Connection Failed -- The network connection is unreachable or the gateway is unresponsive.  Check the network connection and reconnect

Display

Description

The user's computer is not able to reach the gateway.  This may be due to several reason, but is likely an issue with the user's home network or ISP.

Consider investigating these specific items to identify and resolve the issue.

• The user's computer is configured to use a proxy server that is not permitting the communication to the GlobalProtect gateway
• The user's home network router may be filtering or blocking the needed IPSec communications to the GlobalProtect gateway.  

Resolution

Option A - Check Windows Services

Verify that the "PanGPS" and "Windows Management Instrumentation" services are set to Automatic with status of Running

Option B - Check for other conflicts with network traffic

Identify and remove the system, device, or configuration that is preventing the flow of the IPSec communications.

Connection Failed -- The network connection is unreachable or the portal is unresponsive.  Check the network connection and reconnect

Display

Description

The user's computer is not able to reach the portal.  This may be due to several reason, but is likely an issue with the user's home network or ISP.

Consider investigating these specific items to identify and resolve the issue.

• The user's computer is configured to use a proxy server that is not permitting the communication to the GlobalProtect portal
• The user's home network router may be filtering or blocking the needed IPSec communications to the GlobalProtect portal.  
• The user's computer may have manual route entries in a host table or other similar manual routes that are not automatically updated to resolve to the current portal IP address.

Resolution

Option A - Check Windows Services

Verify that the "PanGPS" and "Windows Management Instrumentation" services are set to Automatic with status of Running

Option B - Check for other conflicts with network traffic

Identify and remove the system, device, or configuration that is preventing the flow of the IPSec communications.

Connection Failed -- Failed to verify certificate

Display

Description

The user is able to successfully authenticate and connect to the GlobalProtect (GP) Portal.  However, after retrieving the latest configuration from the portal, the GP agent is unable to establish a VPN tunnel to the GlobalProtect gateway.  Because of a cached portal configurations, the user may not even be presented with a login prompt.  Regardless, the same "Failed to verify certificate" error message will be presented to the user.

A network-based system or software installed on the affected computer is intercepting the SSL certificate from the GP gateway, which is intended to be used by the GP agent, and preventing a successful connection to the gateway.  The SSL interception is likely not a malicious action, rather a by-product of a security software agent or enterprise security service at the user's local network.  These cases are not uncommon for enterprise networks and enterprise managed computers. 

Resolution

The GP agent log bundle will contain information about the device/service that has intercepted the SSL certificate. The Cyber Network Defense group can analyze this log bundle to help identify the conflicting system.

1.  Place the GP agent logging to the "Dump" Logging level - KB0017942: How do I change the GlobalProtect agent logging level?

2. Attempt a connection to the GP gateway, wait until the Failed to verify certificate error message is observed.

3.  Collect the GP agent log bundle - KB0016086: How do I collect the GlobalProtect agent log bundle?

4.  Open a new ServiceNow Incident and assign to "Firewall and Security Team" assignment group.  Attach the log bundle to the ticket.

Connection Failed -- Could not connect to the GlobalProtect service

Display

Description

The issue has been observed on both Mac and Windows computers and is caused by a corrupted installation or software that interferes or prevents the PanGPS service from starting on the computer.

Resolution

The primary way to resolve the issue is to uninstall and reinstall the GlobalProtect agent software on the computer. 

Option A - Reinstall the GlobalProtect agent.

1. Download the currently supported GlobalProtect agent version from the Penn State Software Request website
   https://softwarerequest.psu.edu/
2. Run the installer and select the option to uninstall the software.
3. Reboot the computer then run the installer again selecting the option to install the software
   
   1. For Mac computers be sure to select the option to enable system extensions for GlobalProtect
   2. For Windows computers verify the "PanGPS" and "Windows Management Instrumentation" services are running with startup type set to automatic

Option B - Check the computer for any software that may be preventing startup applications.

1. Performance enhancing software is sometimes used to control startup applications
2. Antivirus or Malware software may also prevent applications from running at startup
3. Verify that Palo Alto Networks is enabled to run in "Login Items" under System Settings -- General

Connecting...  --  Still Working...

Display

Description

The "PanGPS" service did not start correctly, or the installation was not successful.

Resolution

Manually start the "PanGPS" service on a Windows computer.  If the service is already running or is not able to be manually started, then the GlobalProtect VPN agent must be reinstalled.  Be sure to uninstall the GlobalProtect agent, reboot the computer, install the GlobalProtect agent, then reboot the computer again.

The latest PSU preferred GlobalProtect VPN agent can be downloaded from softwarerequest.psu.edu

Web Login Service - Stale Request

Display

Description

The GlobalProtect Remote Access VPN utilizes Penn State's WebAccess system for authentication.  The authentication workflow loads the WebAccess authentication page into a browser kiosk-mode window. The connection to the WebAccess login page is initiated from the computer's network interfaces.  This traffic is not redirected through, tunneled through, or initiated from the GlobalProtect VPN systems.  So, issues connecting to WebAccess are in the path between the originating computer and the WebAccess system located in Penn State's University Park or Hershey Data Centers.

Resolution

• Verify that there are no local browser or system issues on the originating computer
• Ensure the ability to load https://webaccess.psu.edu in a web-browser, and authenticate with PSU credentials including Microsoft MFA.
• Ensure the ability to load https://login.microsoftonline.com in a web-browser. Enter PSU username in format of userid@psu.edu (ex. abc123@psu.edu) and ensure that the page redirects to webaccess.psu.edu
• Verify no local LAN, WiFi, or ISP connectivity issues are present on the originating computer side of the connection. (ping, MTR, Win-MTR, etc. to various Internet destinations)
• Verify a reliable and error-free Internet path is available from the originating computer to Penn State's network.(ping, MTR, Win-MTR, etc. to vpn.psu.edu)  

Script Error - An error has occurred in the script on this page.

Looks like something went wrong.  Please wait a few minutes and try again.  If the problem persists, contact your IT help desk.

Display

Description

When using the GlobalProtect VPN app on the same Android device that is also receiving Microsoft MFA Security push notifications, sometimes the VPN connection fails with the message Looks like something went wrong.  Please wait a few minutes and try again.  If the problem persists, contact your IT help desk.

Resolution

Do not navigate away from the GlobalProtect VPN application to accept the Microsoft MFA Security push notification.  Instead, pull down the Microsoft MFA Security push notification from the Notification Bar, then click Approve.  Do not click the Microsoft MFA Security push notification to open the Microsoft MFA Security App. 

Authentication prompt is for another organization other than Penn State

Display

Description

When using the GlobalProtect VPN agent on a Windows computer using accounts for more than just PSU, sometimes the VPN does not present the PSU authentication window and only shows the other organization authentication window. 

Resolution

PSU credentials should be listed under Accounts --- Access work or school.  If needed remove other organizations and add the PSU account here.

If multiple user accounts or the wrong user accounts are configured under the user profile for "Access School or Work" this will cause GlobalProtect to select an account to attempt to connect for SSO. If GlobalProtect is selecting the wrong account then you may need to remove the additional accounts and only leave the PSU account for GlobalProtect to connect with the appropriate login prompt for PSU.   Refer to KB0017503 - GlobalProtect Remote Access VPN - Why can't I change the GlobalProtect login user name? for specific instruction on the steps to check the settings.
