Authentication failed with OpenVPN client on Windows

Post by milpool » Fri Jun 01, 2018 8:40 pm

I can't get the OpenVPN Connect client on Windows 10 to connect to SoftEther VPN server (also running on Windows 10) and getting "Authentication failed". The OpenVPN clients on both macOS and iOS can connect. I'm using the default OpenVPN remote access ovpn config file. Here is the SoftEther server log:

Ok so I just got the OpenVPN GUI for Windows to connect. I'm curious why the OpenVPN Connect Client on Windows isn't working.

Could you show the log of the client?
