Setting up Unison between 2 droplets

I want to synchronize a directory from one server to another using unison with ssh. i do have iptables running but ssh and scp work between the servers. I am also using an alternate port for ssh. When I run the testServer command, it ends with exits status 0 and no files have been replicated. I have tried touching files on either side but no luck.

here is a sample of the unison call and results followed by a test ssh call and results:

server1_user@server1:~/.unison$ unison -testServer /home/server1_user/downloads/ ssh://unison@<server2-ip>//home/unison/unisontest -sshargs '-p 22222 -i /home/server1_user/.ssh/id_unison -vvv' -debug all
