SoftEther VPN User Forum

Hi,

I installed a SoftEther server on Windows 2012 R2 in my network and activated VPNAZURE.

When using a Windows 8.1 client I can access my network using the SoftEther VPN Client.

But when using the built-in VPN-connection of Windows 8.1 I recieve an Error 734.

The Serverlog shows:

2014-06-17 12:25:03.225 SSTP PPP Session [XXX.XXX.XXX.XXX:59810]: A PPP protocol error occurred, or the PPP session has been disconnected.

Do you have any hints how to troubleshoot?

Best regards
Tobi

Is your SSTP setting same as this instruction?

And, please check the DHCP setting.
