There was a problem connecting to the server, it has not responded.
First, make sure your device is connected to the Internet.
Also, check that the server address is entered correctly, and that the computer is running an FTP Server.
If the FTP Server is running on a different port than the default, make sure to add the port number on the previous page. Add :## to the server address, so if the port is 2121, you might have an address: ftp.myserver.com:2121
Note: If you are connecting to a computer on your home network, you may need to add some "Port Forwarding" settings on your router.
