Check Point SNX Stopped working after 25H2 Update

JoonaL — Thu, 09 Oct 2025 07:08:36 GMT

Hello!

I have problem with SNX. After i update windows to 25H2, SNX stopped working. I tried reinstall java, snx and Mobile Access portal agent. I turned off another vpn so that is not the problem. SNX says is connected, but to website i try to connect with vpn, never opened it says the website did not respond too quickly or IP doesnt found. I tried to edit regedit with that

> reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\cpextender" /v "MetricSetMethod" /t REG_DWORD /d 1 /f

Step 2: Restart the SNX service by typing in CMD:

> net stop cpextender

> net start cpextender

Step 3: Login the Mobile Access Portal and check the SNX connection again.

Regards,

But that doesnt work either. Any ideas what to try next?

Hello,
25h2 is not fully supported.
sk115192 - Check Point Endpoint Security Client Support Schedule for New Operating Systems

SNX is not technically an integral part of the Endpoint Client. But they are related.

General schedule for supporting new Operating Systems (Windows/macOS) Phase 1: Development starts with the first available dev build Phase 2: Early Availability clients within 3 weeks of OS GA Phase 3: GA release within 2 months of OS GA
