Could not determine IPv4/IPv6 protocol.
Kindly anyone help me to how trouble shoot this error.
I am using pfsense 2.4.4 ,my server port 1194 is open. Both internal and external.

It is not an error and it falls back to IPv4.

You can explicitly chose protocol by --proto option
Where option can be: udp, udp4 or udp6 .. or tcp, tcp4 or tcp6

The manual has this:

proto
indicates the protocol to use when connecting with the
remote, and may be "tcp" or "udp".

For forcing IPv4 or IPv6 connection suffix tcp or udp
with 4/6 like udp4/udp6/tcp4/tcp6.

Could not determine IPv4/IPv6 protocol. Using AF_INET6

[TinCanTech]

It is not an error and it falls back to IPv4 .. but in your case it is falling back to v6

We do not support pfSense .. they have their own forum.

If you want to learn about openvpn try the howto .. it is very easy to find ..
