## Error message
```text
Connectivity with the VPN service is lost
```

## TL;DR
The Endpoint Security client lost contact with its own local VPN service. Restart the Check Point Endpoint Security service, check for conflicting VPN clients or endpoint agents, and repair the installation if the service will not stay running.

## Steps
1. Open the services list and check the Check Point Endpoint Security service state.
   Expected: You see it stopped or in a failed state.
2. Restart the service and watch whether it stays running.
   Expected: The service starts, or it dies again, which points at a conflict.
3. Look for other VPN clients, endpoint agents, or recent updates that could conflict, and pause or remove the conflicting one.
   Expected: The conflict is identified.
4. Run a repair of the Endpoint Security client and reconnect.
   Expected: The client connects and the service stays running.

## When to use
- The exact message appears on a machine where the client previously worked
- The service stops repeatedly after starting
- The failure followed another VPN client install or an OS update

## When not to use
- The gateway rejects the connection (gateway-side issue)
- The client never installed correctly (clean install instead)
- The error is about the site or gateway, not the local service

## Why this happens
Check Point splits the UI from a privileged VPN service; the UI reports this message whenever the service is gone. Endpoint security suites, duplicate VPN clients, and OS updates commonly kill or block the service, so the fix is local to the machine.

## Edge cases
- Two Check Point components from different packages can fight over the service; keep one managed installer.
- A repair keeps policies and certificates, while a full reinstall may need re-enrollment.
