Starting sometime over the weekend, SSL VPN clients are no longer able to connect. The client tried to reconnect over and over but it never connects. There was a firmware upgrade recently. Not sure if it coincided with the issue or not.
This is what shows up in the server logs. It's interesting that it shows an non-OpenVPN client protocol. I'm connecting using the Sophos VPN Client. I reinstalled to make sure it was the latest version. No luck. Any idea what's happening?
