I am installing SoftEther on a Windows Server 2019;
After installation, I did a double click on "VPN conection" and get the following error message:
"Protocol error ocurred. Error was returned from the destination server"

the installation is standard, port 443
Direct tcp/ip conection
server admin mode

any idea ??
