I'm getting this error in the logs with debug enabled.
pid=0 DATA len=0
Done some research on this and came up with running
nc -u -v vpnserver 53
It comes back successful
Was also suggested that I change the WANs MTU to 1400.
I guess I could run Wireshark and see how this traffic is behaving.
Thanks for your time and attention,
Its probably your TLS session being denied. What logs are you getting on the OpenVPN Server side?
