Unable to create any VPN site from Windows 10 Home

Dear all!

I'm trying to connect to some corporate VPN from my Windows 10 Home (1803) machine. For connection I use CheckPoint Mobile 80.85. I would like to point out that I'm an outsourcer and I have no idea what is VPN server configuration, I just've got an instruction from some company. I'm an IT guy but not a specialist in VPNs, network, security. So I'm unable to connect to this VPN from any Windows 10 Home machine. When I try to create a new site in client I've getting an error: Failed to create new site. Site is not responding. This problem persists on any Windows 10 Home machine which I've tried (I've tried 3). But I can connect perfectly to this VPN from Windows 7 Home or Windows 10 Pro.

The most interesting part of log is below:

As you can see there is an initial fail of WinApi function InitializeSecurityContextA and then a cascade failure of the software.

Does anybody have any clue? I've tried to play with build in firewall, certificates, older versions of CheckPoint but nothing helped. I would appreciate any help.

Re: Unable to create any VPN site from Windows 10 Home

This is probably something that the remote end will have to fix.

Re: Unable to create any VPN site from Windows 10 Home

Thank you for replay.

But I've used the same client software version everywhere (Win 7, Win10 Pro, Win10 Home). It doesn't work in 10 Home only.

Anyway I have no access to server side and I'm unable to check protocol version...

Re: Unable to create any VPN site from Windows 10 Home

Not sure why Win 10 Home makes a difference, but a difference in allowed TLS versions is exactly what the symptoms point to.

Specifically these errors:

[ 3896 4356][2 Dec 16:23:05][cpwssl] cpWinSSL_fwasync_connected: SSL failure: SSL negotiation error.
[ 3896 4356][2 Dec 16:23:05][cpwssl] cpWinSSL_fwasync_close: closing - conn - 0x2a1eee8
[ 3896 4356][2 Dec 16:23:05][] fwasync_close: close(1924): Unknown Winsock error (10038)

I believe what TLS versions are offered is a function of the Windows OS itself.

What is accepted on the server side is a function of the remote end.

If you use Wireshark or similar to observe the communication between the endpoints, you should see this difference.

How to fix it? Not sure, but I believe there are registry settings you can tweak in the Windows OS.

What you will tweak them to will depend on what you observe with Wireshark.

Re: Unable to create any VPN site from Windows 10 Home

I've run a WireShark. From the capture I can see that Client & Server use TLS 1.2, server hello is ok but then...

Possible this will help: Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings - Microsoft Community 

Am curious what the difference in setting between Win 10 Pro and Win 10 Home.

Ha, this stuff I did at first... Even had to install IE because only Edge was present. TLS was on. Didn't help.

Re: Unable to create any VPN site from Windows 10 Home

Expand the Client Hello and Server Hello packets in the screenshot.

Perhaps we can see some clue what's missing in the TLS negotiation.

Hi,

thank you for your time.

I've attached a WireShark captured TLS hello packets in pcapng format.
