[VPN] Cannot access computer in the same network, through VPN

I have set up an SSTP VPN server on a Windows Server 2019 machine, which is actually an AWS EC2 instance with private ip in the 10.10.0.0/16 subnet.

I can connect to it via standard VPN client , the one built-in in my Windows 10 home computer, and when i am connected to the VPN i also have assigned an address in the same subnet: 10.10.0.0/16 

I have tried connecting via Putty/SSH to a Linux EC2 instance on the same subnet, but the IP was not reachable from my home.

But i have successfully connected to it via ssh command from the VPN Server.

Why not from my home PC?

I am sure i am missing some VPN server configuration.

Thanks
