SSL VPN stopped working
We use the WG SSL VPN tool to connect into our office. One of my colleagues has reported that it's suddenly stopped working. I asked him to uninstall, and download afresh and reinstall, but it won't make a VPN connection.
He's running Win 10.
Everyone else can still VPN in.
Here's the log file... anyone got any ideas please?
