This line of thought is focusing on the remote server's certificate. Are we assuming that my client certificate has to match (not sure if servers can have more than one)?

I would double check that your FTPS server is running on port 21.
990 is the standard. Sometimes it's on 21.
Also, you may need to look closer at the docs if you're using TLS.. it may be something like this:
s_client -connect yourserver:21 -starttls ftp
This should load a screen showing your cert that you can copy and paste into a text docuement.
Again, this is covered here:
http://docs.bvstools.com/home/ssl-documentation/openssl
The examples shown are for SMTP using SSL and SMTP using TLS. Should be very similar to your case, just FTP instead.
TLS requires a little more communication before you get the certificate information than just plain SSL, which is why openSSL has the -starttls option.
