Using Coda to access server SSH/sFTP

Question

Hi,

I have a VPS server and I lock down to only expose 3 ports 80, 443 and 22222 for ssh. So far I can connect to the server using Terminal (Mac) and Panic Transmit, but when I try to connect using Panic Coda the connection fail. What I am doing wrong?

I see Coda support sFTP and I can connect on Coda to the SSH, but not to the sFTP.

Ideas? Work around?

Thank you
