GlobalProtect can show “Could not connect to the GlobalProtect service”, “Connection Failed”, or “Cannot connect to service, error: 61” even when your internet connection works. These messages usually describe a failure between the GlobalProtect interface and its local PanGPS service—not automatically a problem with your VPN portal, gateway, password, or internet connection.
Use the checks below to identify which part is failing before reinstalling anything. Windows and macOS use different service mechanisms, so follow the section for your computer.
First, identify whether the local service is running
GlobalProtect’s user interface communicates with the PanGPS service over the loopback address 127.0.0.1. PanGPS should listen on local TCP port 4767.
Windows
- Open Command Prompt. You do not need to test the VPN portal first.
- Run:
netstat -an | find "4767"A working listener should look similar to:
TCP 127.0.0.1:4767 0.0.0.0:0 LISTENINGmacOS
Open Terminal and run:
netstat -an | grep 4767Expected output includes:
tcp4 0 0 127.0.0.1.4767 *.* LISTEN| Result | What it means | Next step |
|---|---|---|
| No listener on port 4767 | PanGPS did not start correctly, or the installation/operating-system configuration is interfering with startup. | Follow the Windows or Mac service-start checks below and inspect/reinstall the client if necessary. |
| Port 4767 is listening | PanGPS started, but the UI may be blocked from reaching it. | Test the local connection and check endpoint-firewall rules. |
| Local service works, but the portal or gateway fails | This is not primarily a “service not running” problem. | Troubleshoot the portal, gateway, authentication, certificate, or network path separately. |
These local-service checks are based on Palo Alto Networks’ troubleshooting guidance for PanGPA-to-PanGPS communication (Palo Alto Networks).

Windows fixes
1. Check the local firewall if port 4767 is listening
If netstat shows LISTENING, test whether the client can open the local connection. If Telnet is installed, run:
telnet 127.0.0.1:4767If the connection fails despite the listener being present, inspect Windows Firewall and any endpoint-security product for dropped loopback traffic involving GlobalProtect or PanGPS. Palo Alto describes temporarily disabling the workstation firewall only as a diagnostic test. Do not leave the firewall disabled as the fix.
If disabling the firewall makes GlobalProtect work, turn it back on and have your administrator create the appropriate exception. Corporate endpoint-security software may continue blocking the connection even when Windows Firewall is not responsible.
2. Restart Windows and test again
A reboot is worth trying after an interrupted GlobalProtect update or a Windows update, but reopening the GlobalProtect window is not the same as restarting PanGPS. The interface and service are separate processes. After restarting Windows, repeat the port check rather than assuming the service recovered.
3. Use the complete reinstall procedure for a damaged installation
Use this procedure when PanGPS repeatedly fails to start, a GlobalProtect upgrade was interrupted, drivers appear corrupted, or simpler checks have not helped. It requires administrator access and modifies Windows Management Instrumentation data and the registry. Back up important data and involve your IT administrator on a managed work computer.
- Press
Win + R, typeservices.msc, and press Enter. - Find Windows Management Instrumentation (WMI), right-click it, and select Stop.
- Delete the contents of:
C:WindowsSystem32wbemRepositoryDeleting the WMI repository is a destructive system-management operation. It is not a routine first fix for every GlobalProtect connection error.

- Return to
services.mscand confirm that WMI is running.
This sequence comes from Palo Alto Networks’ documented Windows cleanup procedure (Windows uninstall and reinstall guidance).
macOS fixes
1. Allow Palo Alto Networks to run in the background
On macOS Ventura or later, macOS can prevent the background component that GlobalProtect needs to communicate with its service. If the menu bar app shows Connection Failed or says it cannot connect to the service:
- Open the Apple menu and choose System Settings.
- Open General.
- Select Login Items.
- Under Allow to run in the Background, enable Palo Alto Networks.
- Quit and reopen GlobalProtect, or restart the Mac.
This is the current Ventura-and-later permission path. Do not treat older kernel-extension approval commands as a universal replacement for this setting. The relevant documented instructions are available from UC Berkeley’s GlobalProtect support guidance.
2. Check that the GlobalProtect processes exist
In Terminal, run:
ps -ef | grep -i globalprotectPalo Alto expects to see processes corresponding to:
/Applications/GlobalProtect.app/Contents/Resources/PanGPS
/Applications/GlobalProtect.app/Contents/MacOS/GlobalProtectIf neither process appears, continue with the file and launch-agent checks.
3. Check the application files and launch agents
Run these commands:
ls -lth /Library/LaunchAgents/com.paloaltonetworks.gp.pangpa.plist
ls -lth /Library/LaunchAgents/com.paloaltonetworks.gp.pangps.plist
ls -lth /Applications/GlobalProtect.app/Contents/Resources/PanGPS
ls -lth /Applications/GlobalProtect.app/Contents/MacOS/GlobalProtectIf any file is missing, the installation is incomplete. Palo Alto’s documented action in that situation is to uninstall and reinstall GlobalProtect rather than manually creating replacement files.

4. Check whether launch agents are disabled
First obtain your logged-in user’s numeric UID:
id -uSuppose the command returns 501. Replace 501 below with your actual result:
launchctl print-disabled user/501 | grep pangpBlank output, or output showing both services as false, is expected:
"com.paloaltonetworks.gp.pangps" => false
"com.paloaltonetworks.gp.pangpa" => falseIf the agents are not disabled, load them:
launchctl load /Library/LaunchAgents/com.paloaltonetworks.gp.pangps.plist
launchctl load /Library/LaunchAgents/com.paloaltonetworks.gp.pangpa.plistIf either service is shown as disabled with true, enable and load it:
launchctl load -w /Library/LaunchAgents/com.paloaltonetworks.gp.pangps.plist
launchctl load -w /Library/LaunchAgents/com.paloaltonetworks.gp.pangpa.plistThen check again:
ps -ef | grep -i globalprotectA Load failed message can mean the service is disabled, a plist is missing, the installation is incomplete, or macOS is restricting launch control. Check the files and disabled-state output before jumping to a reinstall. If the services still do not start, review macOS Security settings and your organization’s endpoint-management restrictions.

Mac users on GlobalProtect 6.0 through 6.0.4
Palo Alto documented a startup race in GlobalProtect App 6.0 and later: PanGPA could start before PanGPS, causing the service error even though the application was installed. The issue was fixed in GlobalProtect 6.0.5 under defect GPC-16392, which added a grace period so PanGPS could launch first.
If the problem began after installing an older 6.0 release, update to a version approved by your VPN administrator. Do not install a random public package if your organization supplies a customized portal-specific client.
When the service is running but the VPN still will not connect
Once port 4767 is listening and the local client can reach it, stop treating the issue as a service-start failure. Check the separate VPN path:
- Confirm the portal address is correct.
- Check whether the portal or gateway is reachable from the current network.
- Verify credentials, multifactor authentication, certificates, and device posture requirements.
- Test another network if permitted by your organization.
- Ask the VPN administrator whether the gateway is rejecting the device or user.
Being online only proves that general internet access works. It does not prove that the GlobalProtect portal or gateway is reachable, and conversely, a portal problem does not prove that PanGPS is stopped.

FAQ
Why does GlobalProtect say the service is not running when my internet works?
The GlobalProtect interface communicates with the local PanGPS service over 127.0.0.1:4767. That local communication can fail independently of normal internet access. Check whether port 4767 is listening before troubleshooting the VPN portal.
What does “Cannot connect to service, error: 61” mean?
It indicates that the GlobalProtect UI could not connect to the local PanGPS service. It does not, by itself, prove that your credentials, VPN gateway, portal, or internet connection is the cause.
How do I know whether PanGPS is running?
On Windows, run netstat -an | find “4767” and look for 127.0.0.1:4767 in LISTENING state. On macOS, run netstat -an | grep 4767 and look for a LISTEN result.
What should I do if port 4767 is listening but GlobalProtect still reports a service error?
Test the local connection with telnet 127.0.0.1:4767 if Telnet is available. If it fails, check Windows Firewall, macOS firewall controls, and endpoint-security software for blocked loopback traffic.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsWhy is Palo Alto Networks missing from Mac Login Items?
The GlobalProtect installation may be incomplete, the background component may be restricted, or an upgrade may have removed or damaged its launch agents. Check the two plist files under /Library/LaunchAgents and reinstall if required.
Should I delete the Windows WMI Repository immediately?
No. Deleting C:WindowsSystem32wbemRepository is a destructive operation that Palo Alto places inside a complete uninstall/reinstall procedure for corrupted installation or driver-related data. It is not a routine first fix.
Can restarting the GlobalProtect window restart the VPN service?
Not necessarily. PanGPA/GlobalProtect and PanGPS are separate processes. Verify the PanGPS listener on local port 4767 instead of assuming that reopening the interface restarted the service.
The Bottom Line
Start with the local test: GlobalProtect should have PanGPS listening on 127.0.0.1:4767. No listener points to a service-start, installation, launch-agent, or operating-system problem. A listener that cannot be reached points to local firewall or endpoint-security interference. If the listener works, troubleshoot the portal or gateway instead. Use the complete Windows WMI cleanup or macOS reinstall only when the simpler checks identify a damaged or incomplete installation.
