Remote Logging by FTP fails.

I'm trying to send log archives to a local FTP server but they never get sent and the FTP server logs never show a connection attempt.
The FTP server listens on a non standard port, but I have that set up as a service definition.
Every morning I get an email saying the remote archive failed.
The logging log file ans the below entry.

WARN: couldn't store logfile archive remotely! Error code was: 1
Remote log file storage failed
INFO: * processing ARM configuration ...
INFO: can't read ARM config '/etc/arm.conf':

Any thoughts?
