Setting OpenVPN Ping Interval to 100 crashes OpenVPN server
When I went to VPN>OpenVPN>Servers>Edit
and changed the keepalive ping interval from 10 to 100,
my vpn immediately quit working. The services>status widget on the dashboard showed the openvpn service wasn't running, and wouldn't start when I clicked start. When I changed the interval back to 10, it started. It's TUN and all other settings are default I think.
Look at the OpenVPN logs they will tell you why it was failing to start.
