OK, so the problem is that OpenVPN is not starting, even though it shows up as green and RUNNING on the OpenVPN page.
We need to look at the OpenVPN logs. Press the “Stop OpenVPN Server” button and confirm that the status changes to red and STOPPED. Then press the “Start OpenVPN Server” button and confirm that it goes green and RUNNING.
Then use the following command to filter the log for OpenVPN.
less /var/log/messages | grep openvpn
Near the end you should find the commands and messages related to the stopping and then starting of the OpenVPN server that you did above. You can use the timestamp of the log entries to select the right portion of the logs. If you can paste those messages (redacting any public IP’s or other sensitive items that you don’t want to disclose) then we can see what clues it gives as to why the server is not starting.
