New User; unable to connect OpenVPN

Post by ehbowen » Wed Jul 12, 2023 5:38 pm

I'm trying unsuccessfully to configure and connect to an OpenVPN server on a Synology NAS device (DSM 7.2, Synology VPN Server) on a network where I have administrative access. However, while I'm asked for my username and password and I've verified that they are correct, I'm not being connected to the network. I'm new to OpenVPN and I'd like help in troubleshooting the problem.

Here's a snippet of the connection log:

Code: Select all
