SonicWall Endpoint Security (EDR) Installation Failure Due to System Time Error Behind a SonicWall
Description
SonicWall Endpoint Security/EDR installation fails with a "System time is incorrect" error even though the endpoint's date, time, time zone, and Windows Time service are configured correctly.
Resolution
1.Verify that the endpoint has accurate date, time, and time zone settings.
2. Ensure the Windows Time (W32Time) service is running and successfully synchronized with a valid time source.
3. If the error persists despite successful time synchronization, perform network isolation testing by connecting the endpoint to an alternative internet connection (for example, a mobile hotspot).
4. If the installation succeeds on the alternate network, investigate the original network and SonicWall security services for interference with the installation process.
5. Configure the appropriate CFS exclusion for the required EDR-related traffic, domains, or destinations.
6. add the CFS exclusion on firewall *.endpoint-us.sonicwall.com
