The problem looks like the server is sending an internal IP address in response to passive command instead of external, Internet addressable IP address.  Server is telling client to connect on IP 10.26.4.63  Based on the IP address this is clearly an internal address that can only be seen by the servers network.  This is why you are unable to connect to start the transfer.

To fix you may either:

a.  Ask them to reconfigure server to use external IP instead of internal IP allowing you to connect.

b.  Use active FTP mode in your FTP client instead of passive FTP mode. If you are behind a firewall you may have problems here though.
