OpenVPN Auth issue

Post by krikaleak » Mon Oct 15, 2018 4:23 am

hey all,

I've setup a Softether VPN server and generated a openvpn profile using the tool on Softether. every time I try to connect from the OpenVPN android app using the profile and a user I created I keep getting a Auth Failed message on the client, and the server has this log. I can't figure out the issue because according to the log it looks like it does authenticate. Please let me know if you have any idea what's going on! Thank you!! P.S. I edited all external IP's.

Hello,

In that case it's not an authentication issue, the OpenVPN client fails to connect because you don't have a DHCP server:

Code: Select all
