SSTP + Windows 7

Hello,

i try to setup an SSTP Tunnel from an Windows 7 Client to an Mikrotik RB433AH (v5.23). The setup was sucessfully, but now i have a problem with the certificate on the client. I’ve imported the CA on the Local Computer Certificate Store in the “Trusted Root Certification Authorities”, and also on the Mikrotik. When i try to connect with the Router, i get the following error:

Error 0x800B0110: The certificate is not valid for the requested usage.

I have also enabled all purposes for the certificate in the certificate properties.

Does anyone here in the forum has got the same or an similar issue? What can i do in that case?

Thanks in advance.

Kind regards
