I have openvpn on ubuntu 16.04 to accept connections on tcp 443 (which works), but when I setup a second config with port 1194 udp, it's giving me:
TLS Error: TLS key negotiation failed to occur within 60 seconds
(check your network connectivity)
TLS Error: TLS handshake failed
Console Output of sudo iptables -S
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
-A INPUT -s 10.9.0.0/24 -j ACCEPT
Console Output of sudo iptables -t nat -S
