Help please --> SoftEther in RDP

[vpn_newbie]

I am using the SoftEther Open Source Project VPN client list

I installed SoftEther in my RDP (winServer 2016)

After connect (RDP) to the winServer 2016, I then open the SoftEther, and I want to use VPN in the winServer 2016.

As soon as SoftEther connect, my RDP connection got lost.

Where in the VPN client list I can change the setting and what do I need to change please?

I tried many settings, but RDP didnot connect to another PC.
