File is not transferred to different FTP server

We have a web application where we create xml file in web application and then sent it to our FTP server. When we deploy it on Xojo cloud we are not to send the xml file to our server.
How can we do that?

Thanks in advance

Make sure you are opening the firewall port(s) that you need.

In Windows firewall on my machine, under inbound rules I created a new rule under TCP protocol which allowed 21 and 22 port for Local and remote. But Still file is not being transferred.
What am i doing wrong?
