Please help.
I have configured Windows server 2012 R2 as VPN server on 443 port. My Windows clients can connect to SSTP VPN.
But I do not know how to configure Android 4.2.2 device. So far I have installed OpenVPN for Android. In connection I added VPN server certificate (also tried root CA certificate and Intermediate Issuer certificate). Mybe there is nay other app.
On tablet I got log
