That is not a successful response.

Try this:

# echo "foobar" | nc -l localhost 12345 &

# openssl s_client -tls1_2 -connect localhost:12345

and compare the output to what you have above.

Then try:

# echo "foobar" | nc -l -c -C /etc/ssl/server.crt -K /etc/ssl/private/server.key localhost 12345 &

# openssl s_client -tls1_2 -connect localhost:12345

To see what a successful response looks like.
