Hi Isaac,
I see you are trying to use ftp job, but you are connecting to port 22, which is the default port for sftp. Are you sure your ftp server is running on port 22? Also please confirm if you are trying to use sftp or ftp transfer.
Searching past cases in our internal database, I see references to System Agent R11.3 SP4 Incr 2 where this issue is fixed, but I could not find this information in our release notes. I would try to fix the port issue first. If that does not help, try with a recent agent.
Regards,
